Title of Invention: Curable Silicone Compositions Abstract: The invention relates to a curable composition, containing (A) at least one polyorganosiloxane, which has at least one hydroxy group bound to a silicon atom, (B) at least one silane of the formula (1): Si(R1)m(R2)n(R3)4-(m+n) (1), as defined herein, (C) at least one aminosilane, and (D) at least one tin compound, whereby the molar ratio of the aminosilane to the tin compound is 1:1 to 50:1, as well as to the preparation and use thereof. Detailed Description: The invention relates to curable compositions based on a curable polyorganosiloxane, which contain apart from the polyorganosiloxane a special silane crosslinker, an aminosilane, and a tin compound as a curing catalyst, whereby the aminosilane and tin compound are used in a defined quantitative ratio. These compositions are notable particularly for an excellent storage stability. The invention relates furthermore to a method for preparing the curable compositions as well as the use thereof. Silicone polymers (polyorganosiloxanes), particularly polydialkylsiloxanes such as polydimethylsiloxane (PDMS), have great importance in the production of adhesive, sealing, coating, and insulation materials. Among these, those that vulcanize at low temperatures and under ambient conditions constitute a not insignificant share of the market. Typical formulations contain a reactive polyorganosiloxane. As a rule, this concerns a silanol-terminated polyorganosiloxane, whereby the polyorganosiloxane has at least one, preferably two hydroxy groups bound to a silicon atom. It is used in combination with a silane-based crosslinker which has hydrolyzable groups bound to the silicon atom. The term curing agent is also used occasionally instead of crosslinker. Within the context of this application, the terms crosslinker and curing agent are synonymous. The polyorganosiloxane and crosslinker can be present as separate components. The polyorganosiloxane is often reacted selectively with the crosslinker, however, to form a modified polyorganosiloxane, and said modified polyorganosiloxane is added to the curable composition. The term endcapping (end group capping) is also used in this regard. This can be carried out optionally in the presence of a catalyst, whereby the catalyst is to mediate the endcapping selectively without simultaneously curing the polyorganosiloxane. Numerous crosslinkers for silicone systems are known. These can be differentiated into acidic, basic, and neutral crosslinkers based on the leaving groups released during hydrolysis. Typical acidic crosslinkers contain acid groups as hydrolyzable groups and release the corresponding acids, e.g., acetic acid, during the crosslinking. Typical basic crosslinkers release amines during the crosslinking. In both cases, aggressive compounds are released during the crosslinking, which can corrode or break down, e.g., metals, stone, or mortar, and which moreover have an intense, often unpleasant odor. Neutral crosslinkers are therefore often used for modern curable silicone compositions. Typical representatives of neutral crosslinkers have hydrolyzable groups, which split off alcohol or oxime during the crosslinking. Alkoxy systems nevertheless have the disadvantage that multiple problems arise in the case of the storage stability of relevant curable compositions and the cured products exhibit only poor adhesion to some materials. Oximosilane crosslinkers, which hydrolyze with the release of an alkanone oxime, usually do not have these disadvantages and are therefore widely used. The most common representative of the oximosilane crosslinkers releases butan-2-one oxime during crosslinking. This is suspected of causing cancer, so that there is an urgent need for alternative neutral crosslinkers. Apart from that, the released oximes also have an intense, foul odor and working with curable compositions, which contain a relevant crosslinker, is perceived as disagreeable by the users. Silane compounds that release α-hydroxycarboxylic acid esters or α-hydroxycarboxylic acid amides during crosslinking, have already been proposed therefore as alternative crosslinkers. The preparation of suitable silane compounds has been long known and is described, for example, by M. M. Sprung in “Some α-carbalkoxyalkoxysilanes,” J. Org. Chem., 1958, 23 (10), pp. 1530-1534. DE 32 10 337 A1 as well discloses relevant silane compounds and the preparation and use thereof in curable compositions based on polydiorganosiloxanes, which have condensable end groups. Hardeners for silicone rubber materials, which have three 2-hydroxypropionic acid alkyl ester groups, i.e., lactic acid alkyl ester groups, are known from EP 2 030 976 A1. Vinyl tris(ethyl lactato)silane is particularly preferred in this case. EP 2 774 672 A1 describes special catalysts for the crosslinking of silicone rubber materials with a crosslinker based on a silane compound with lactate groups. Then again, the crosslinker can be the compounds known from EP 2 030 976 A1. Crosslinkers are also disclosed, however, which have only one, two, or also four 2-hydroxypropionic acid alkyl ester groups. Although the use of a crosslinker based on a silane compound with lactate groups or similar α-carbalkoxyalkoxy groups is associated with many advantages, these crosslinkers have not yet been able to gain acceptance in practice. This is due in particular to the difficulty of formulating curable silicone-based compositions, containing these crosslinkers, such that a sufficient storage stability is achieved. The storage stability deteriorates drastically specifically in the presence of other conventional and frequently indispensable components of such compositions, particularly of curing catalysts and adhesion promoters. It is therefore an object of the present invention to provide curable compositions based on polyorganosiloxanes, which allow the use of crosslinkers, releasing α-hydroxycarboxylic acid esters or α-hydroxycarboxylic acid amides during crosslinking, and nevertheless still have an excellent storage stability. The present invention achieves said object by providing curable compositions based on polyorganosiloxanes, whereby the compositions contain, in addition to said crosslinker, at least one aminosilane and at least one tin compound, whereby the molar ratio of the aminosilane and tin compound lies within a narrowly defined range. The subject matter of the invention therefore constitutes curable compositions, containing (A) at least one polyorganosiloxane, which has at least one hydroxy group bound to a silicon atom, (B) at least one silane of the formula (1): Si(R1)m(R2)n(R3)4-(m+n) (1) where each R1 independently stands for: a substituted or unsubstituted alkyl, alkenyl, or alkynyl group; a substituted or unsubstituted cycloaliphatic group or aryl group; a substituted or unsubstituted heteroalicyclic group or heteroaryl group; each R2 independently stands for a group of the general formula (2): OCR42COOR5 (2) where each R4 independently stands for: hydrogen; or a substituted or unsubstituted alkyl, alkenyl, or alkynyl group; R5 stands for: a substituted or unsubstituted alkyl, alkenyl, or alkynyl group; each R3 independently stands for a group of the general formula (3): —OCR62CONR7R8 (3) where each R6 independently stands for: hydrogen or a substituted or unsubstituted alkyl, alkenyl, or alkynyl group; R7 stands for: hydrogen, a substituted or unsubstituted alkyl, alkenyl, or alkynyl group, a substituted or unsubstituted cycloaliphatic group or aryl group, for R8, or a group —(CH2)q—COOR9, where p is an integer from 2 to 10, particularly 2, and R9 stands for a substituted or unsubstituted alkyl, alkenyl, or alkynyl group, or a substituted or unsubstituted cycloaliphatic group or aryl group; R8 stands for a group of the general formula (4): —R10—SiR11o(OR12)3-o (4) where R10 stands for: an alkylene group, optionally interrupted by a heteroatom; each R11 independently stands for: a substituted or unsubstituted alkyl, alkenyl, or alkynyl group; each R12 independently stands for: a substituted or unsubstituted alkyl, alkenyl, or alkynyl group, an acyl group, or a group of the formula (5): —CR132COOR14 (5) where each R13 independently stands for: hydrogen; or a substituted or unsubstituted alkyl, alkenyl, or alkynyl group; R14 stands for: a substituted or unsubstituted alkyl, alkenyl, or alkynyl group; and o independently stands for 0, 1, or 2, and m independently stands for 0 or 1 and n independently for 0, 1, 2, 3, or 4, whereby the sum n+m is a maximum of 4, (C) at least one aminosilane, and (D) at least one tin compound, where the molar ratio of the aminosilane to the tin compound is 1:1 to 50:1. Adjusting the quantitative ratio of the aminosilane and tin compound in the range of the invention assures that the curable composition, on the one hand, has very high storage stability and, on the other, cures reliably and at a sufficient rate after application in the presence of atmospheric moisture even at room temperature (23° C.). A further subject matter of the invention is a method for preparing the curable compositions of the invention, whereby the polyorganosiloxane, which has at least one hydroxy group bound to a silicon atom, the silane of the formula (1), the aminosilane, the tin compound, and optionally at least one further ingredient is mixed together. The invention relates further to the use of a curable composition of the invention or a curable composition prepared according to the method of the invention as an adhesive, sealing, or coating material. A “curable composition” is understood to be a substance or mixture of multiple substances, which is curable by physical or chemical measures. In this regard, these chemical or physical measures can be, for example, the supplying of energy in the form of heat, light, or other electromagnetic radiation, but also simply bringing into contact with atmospheric moisture, water, or a reactive component. The composition thereby changes from an original state to a state that has a higher hardness. Provided reference is made to molecular weights of oligomers or polymers in the present application, the quantities, unless otherwise stated, refer to the weight average, i.e., the Mw value, and not to the arithmetic average. The molecular weight is determined by gel permeation chromatography (GPC) with tetrahydrofuran (THF) as the eluent according to DIN 55672-1:2007-08, preferably at 35° C. Molecular weights of monomeric compounds are calculated based on the respective molecular formula and the known molecular weights of the individual atoms. “At least one,” as used herein, refers to 1 or more, i.e., 1, 2, 3, 4, 5, 6, 7, 8, 9, or more. In regard to an ingredient, the term relates to the type of ingredient and not to the absolute number of molecules. “At least one polymer” thus means, for example, at least one type of polymer, i.e., that a type of polymer or a mixture of a number of different polymers can be used. Together with weight data, the term refers to all compounds of the given type, contained in the composition/mixture, i.e., that the composition contains no other compounds of this type beyond the given amount of the relevant compounds. All percentage data, provided in connection with the compositions described herein, refer to % by weight, based in each case on the relevant mixture, unless explicitly indicated otherwise. “Alkyl,” as used herein, refers to a saturated aliphatic hydrocarbon including straight-chain and branched-chain groups. The alkyl group preferably has 1 to 10 carbon atoms (if a numerical range, e.g., “1-10” is given herein, this means that this group, in this case the alkyl group, can have 1 carbon atom, 2 carbon atoms, 3 carbon atoms, etc., up to and including 10 carbon atoms). In particular, the alkyl can be an intermediate alkyl, which has 5 to 6 carbon atoms, or a lower alkyl, which has 1 to 4 carbon atoms, e.g., methyl, ethyl, n-propyl, isopropyl, butyl, isobutyl, tert-butyl, etc. The alkyl groups can be substituted or unsubstituted. “Substituted,” as used in this connection, means that one or more carbon atoms and/or hydrogen atom(s) of the alkyl group are replaced by heteroatoms or functional groups. Heteroalkyl groups in which 1 or more carbon atoms are replaced by heteroatoms, particularly selected from O, S, N, and Si, are obtained by the replacement of one or more carbon atoms by heteroatoms. Examples of such heteroalkyl groups are, without limitation, methoxymethyl, ethoxyethyl, propoxypropyl, methoxyethyl, isopentoxypropyl, ethylaminoethyl, trimethoxypropylsilyl, etc. Functional groups that can replace the hydrogen atoms are selected particularly from ═O, ═S, —OH, —SH, —NH2 —NO2, —CN, —F, —Cl, —Br, —I, —OCN, —NCO, C3-8 cycloalkyl, C6-14 aryl, a 5-10-membered heteroaryl ring, in which 1 to 4 ring atoms independently are nitrogen, oxygen, or sulfur, and a 5-10-membered heteroalicyclic ring, in which 1 to 3 ring atoms are independently nitrogen, oxygen, or sulfur. “Alkenyl,” as used herein, refers to an alkyl group, as defined herein, which consists of at least two carbon atoms and at least one carbon-carbon double bond, e.g., ethenyl, propenyl, butenyl, or pentenyl and structural isomers thereof such as 1- or 2-propenyl, 1-, 2-, or 3-butenyl, etc. Alkenyl groups can be substituted or unsubstituted. If they are substituted, the substituents are as defined above for alkyl. “Alkynyl,” as used herein, refers to an alkyl group, as defined herein, which consists of at least two carbon atoms and at least one carbon-carbon triple bond, e.g., ethynyl (acetylene), propynyl, butynyl, or petynyl and structural isomers thereof as described above. Alkynyl groups can be substituted or unsubstituted. If they are substituted, the substituents are as defined above for alkyl. A “cycloaliphatic group” or “cycloalkyl group,” as used herein, refers to monocyclic or polycyclic groups (a number of rings with carbon atoms in common), particularly of 3-8 carbon atoms, in which the ring does not have a completely conjugated pi-electron system, e.g., cyclopropyl, cyclobutyl, cyclopentyl, cyclohexyl, cyclobutenyl, cyclopentenyl, cyclohexenyl, etc. Cycloalkyl groups can be substituted or unsubstituted. “Substituted,” as used in this regard, means that one or more hydrogen atoms of the cycloalkyl group are replaced by functional groups.

Examples of aryl groups are phenyl, naphthalenyl, and anthracenyl. Aryl groups can be substituted or unsubstituted. If they are substituted, the substituents are as defined above for cycloalkyl. A “heteroaryl” group, as used herein, refers to a monocyclic or polycyclic (i.e., rings that share an adjacent ring atom pair) aromatic ring, having particularly 5 to 10 ring atoms, where one, two, three, or four ring atoms are nitrogen, oxygen, or sulfur and the rest is carbon. Examples of heteroaryl groups are pyridyl, pyrrolyl, furyl, thienyl, imidazolyl, oxazolyl, isoxazolyl, thiazolyl, isothiazolyl, pyrazolyl, 1,2,3-triazolyl, 1,2,4-triazolyl, 1,2,3-oxadiazolyl, 1,2,4-oxadiazolyl, 1,2,5-oxadiazolyl, 1,3,4-oxadiazolyl, 1,3,4-triazinyl, 1,2,3-triazinyl, benzofuryl, isobenzofuryl, benzothienyl, benzotriazolyl, isobenzothienyl, indolyl, isoindolyl, 3H-indolyl, benzimidazolyl, benzothiazolyl, benzoxazolyl, quinolizinyl, quinazolinyl, phthalazinyl, quinoxalinyl, cinnolinyl, naphthyridinyl, quinolyl, isoquinolyl, tetrazolyl, 5,6,7,8-tetrahydroquinolyl, 5,6,7,8-tetrahydroisoquinolyl, purinyl, pteridinyl, pyridinyl, pyrimidinyl, carbazolyl, xanthenyl, or benzoquinolyl.

A “heterocycloalkenyl” group contains in addition one or more double bonds. The ring however has no completely conjugated pi-electron system. Examples of heteroalicyclic groups are pyrrolidinone, piperidine, piperazine, morpholine, imidazolidine, tetrahydropyridazine, tetrahydrofuran, thiomorpholine, tetrahydropyridine, and the like. Heterocycloalkyl groups can be substituted or unsubstituted. If they are substituted, the substituents are as defined above for cycloalkyl. The curable compositions of the invention contain as component (A) at least one polyorganosiloxane, which has at least one hydroxy group bound to a silicon atom. Preferably, the polyorganosiloxane has at least two hydroxy groups bound to a silicon atom. It is preferred, in addition, that the hydroxy group or hydroxy groups are bound to terminal silicon atoms. If the polyorganosiloxane is branched, it preferably has a hydroxy group at each end. The polyorganosiloxane, which has at least one hydroxy group bound to a silicon atom, is preferably a polydiorganosiloxane, preferably a polydimethylsiloxane. Preferably, therefore, an α,ω-dihydroxy-terminated polydiorganosiloxane, particularly an α,ω-dihydroxy-terminated polydimethylsiloxane is used as the polyorganosiloxane, which has at least one hydroxy group bound to a silicon atom. Particularly preferred are α,ω-dihydroxy-terminated polydimethylsiloxanes, which have a kinematic viscosity at 25° C. of 5000 to 120,000 cSt, particularly 10,000 to 100,000 cSt, and particularly preferably 50,000 to 90,000 cSt. The curable compositions contain the at least one polyorganosiloxane, which has at least one hydroxy group bound to a silicon atom, preferably in an amount of 30 to 90% by weight, particularly preferably in an amount of 40 to 60% by weight, based in each case on the total weight of the composition. If a mixture of a number of polyorganosiloxanes is used, the quantitative data naturally relate to the total amount of the polyorganosiloxanes, which have at least one hydroxy group bound to a silicon atom, in the composition. The curable compositions of the invention contain as component (B) at least one silane of the formula (1): Si(R1)m(R2)n(R3)4-(m+n) (1). In this case, each R1 independently stands for a substituted or unsubstituted alkyl, alkenyl, or alkynyl group; a substituted or unsubstituted cycloaliphatic group or aryl group; or a substituted or unsubstituted heteroalicyclic group or heteroaryl group.

Particularly preferably each R3 independently of one another stands for a group of the formula (3), where one of the R6 groups stands for hydrogen and the second R6 group for methyl, R7 for hydrogen or methyl, and R8 for a group of the formula (4), where R10 is an alkylene group of the formula —(CH2)p—, where p stands for 3, each R11 independently of one another stands for methyl or ethyl, and each R12 independently of one another for methyl or ethyl, and o for 0, 1, or 2, preferably 0 or 1, particularly preferably 0. In a first embodiment, n and m in formula (1) are selected so that the sum n+m is 4. In this case, the silane of the formula (1) contains no R3 group, i.e., no α-hydroxycarboxylic acid amide group. Preferred silanes of the formula (1) in this case are selected from methyl tris(ethyl lactato)silane, ethyl tris(ethyl lactato)silane, phenyl tris(ethyl lactato)silane, vinyl tris(ethyl lactato)silane, tetra(ethyl lactato)silane, and mixtures thereof. In a second embodiment, n and m in formula (1) are selected so that the sum n+m is 3. In this case, the silane of the formula (1) contains at least one R3 group, i.e., at least one α-hydroxycarboxylic acid amide group. Preferred silanes of the formula (1) in this case are selected from compounds, which are obtained by the selective amidation of methyl tris(ethyl lactato)silane, ethyl tris(ethyl lactato)silane, phenyl tris(ethyl lactato)silane, vinyl tris(ethyl lactato)silane, tetra(ethyl lactato)silane, or mixtures thereof with an amine of the formula (7): (HR7N)—R10—SiR11o(OR12)3-o (7) where o, R7, R10, and each R11 and each R12, in each case independently of one another, have the aforesaid general, preferred, and particularly preferred meanings. Particularly preferably, this concerns an amidation product of methyl tris(ethyl lactato)silane, ethyl tris(ethyl lactato)silane, phenyl tris(ethyl lactato)silane, vinyl tris(ethyl lactato)silane, tetra(ethyl lactato)silane, or mixtures thereof with 3-aminopropyltrimethoxysilane and/or 3-aminopropyltriethoxysilane. The curable compositions contain the silane of the formula (1) preferably in an amount of 2 to 7% by weight, particularly preferably in an amount of 4 to 6% by weight, based in each case on the total weight of the composition. If a mixture of a number of silanes of the formula (1) is used, the quantitative data naturally refer to the total amount of silanes of the formula (1) in the composition. The curable compositions can contain the polyorganosiloxane, which has at least one hydroxy group bound to a silicon atom, and the silane of the formula (1) as separate components. It is likewise possible, however, that these components are present in the form of a prepolymer. The prepolymer is a reaction product of the two components. Suitable reactions are known and are also called endcapping. This can be carried out optionally in the presence of a catalyst, whereby the catalyst is to mediate the endcapping selectively without simultaneously curing the polyorganosiloxane. Suitable catalysts are, for example, acids, organic lithium compounds, as they are described, for example, in EP 0 564 253 A1, amines, inorganic oxides, potassium acetate, organotitanium derivatives, titanium/amine combinations, and carboxylic acid/amine combinations. If the polyorganosiloxane, which has at least one hydroxy group bound to a silicon atom, and the silane of the formula (1) are present as a prepolymer, thus the aforesaid quantitative data for polyorganosiloxane, on the one hand, and the silane, on the other, for the prepolymer are to be applied additively. The curable compositions, therefore, contain the prepolymer preferably in an amount of 32 to 97% by weight, particularly preferably in an amount of 44 to 66% by weight, based in each case on the total weight of the composition. If a mixture of a number of prepolymers is used, the quantitative data naturally refer to the total amount of prepolymers in the composition. The curable compositions contain as component (C) at least one aminosilane. Preferably the aminosilane is an aminosilane of the formula (6), (R15R7N)—R10—SiR11o(OR12)3-o (6) where o, R7, R10, and each R11 and each R12, in each case independently of one another, have the aforesaid general, preferred, and particularly preferred meanings, and R15 stands for: hydrogen, a substituted or unsubstituted alkyl, alkenyl, or alkynyl group. R15 preferably stands for hydrogen, a substituted or unsubstituted alkyl group having 1 to 10 carbon atoms, preferably an unsubstituted alkyl group having 1 to 10 carbon atoms, particularly having 1 to 4 carbon atoms, particularly methyl. Particularly preferably, R15 stands for hydrogen or methyl. The aminosilane is preferably selected from 3-aminopropyltrimethoxysilane, 3-aminopropyltriethoxysilane, aminomethyltrimethoxysilane, aminomethyltriethoxysilane, 3-aminopropylmethyldiethoxysilane, (N-2-aminoethyl)-3-aminopropyltrimethoxysilane, (N-2-aminoethyl)-3-aminopropyltriethoxysilane, diethylenetriaminopropyltrimethoxysilane, phenylaminomethyltrimethoxysilane, (N-2-aminoethyl)-3-aminopropylmethyldimethoxysilane, 3-(N-phenylamino)propyltrimethoxysilane, 3-piperazinylpropylmethyldimethoxysilane, 3-(N,N-dimethylaminopropyl)aminopropylmethyldimethoxysilane, tri[(3-triethoxysilyl)propyl]amine, tri[(3-trimethoxysilyl)propyl]amine, and the oligomers thereof, 3-(N,N-dimethylamino)propyltrimethoxysilane, 3-(N,N-dimethylamino)-propyltriethoxysilane, (N,N-dimethylamino)methyltrimethoxysilane, (N,N-dimethylamino)methyltriethoxysilane, bis(3-trimethoxysilyl)propylamine, bis(3-triethoxysilyl)propylamin, and mixtures thereof, particularly preferably of 3-aminopropyltrimethoxysilane, 3-aminopropyltriethoxysilane, aminomethyltrimethoxysilane, aminomethyltriethoxysilane, 3-(N,N-dimethylamino)propyltrimethoxysilane, 3-(N,N-dimethylamino)propyltriethoxysilane, (N,N-dimethylamino)methyltrimethoxysilane, (N,N-dimethylamino)methyltriethoxysilane, bis(3-trimethoxysilyl)propylamine, bis(3-triethoxysilyl)propylamine, and mixtures thereof. The curable compositions contain the aminosilane preferably in an amount of 0.05 to 4% by weight, preferably in an amount of 0.1 to 2% by weight, particularly preferably in an amount of 0.2 to 2% by weight, based in each case on the total weight of the composition. If a mixture of a number of aminosilanes is used, the quantitative data naturally refer to the total amount of aminosilanes in the composition. The curable compositions lastly contain as component (D) at least one tin compound. Preferably, this is an organotin compound or an inorganic tin salt. Tin in these tin compounds is preferably bivalent or tetravalent. Component (D) is added to the composition particularly as a crosslinking catalyst. Suitable inorganic tin salts are, for example, tin(II) chloride and tin(IV) chloride. Organotin compounds (tin organyles) are used preferably as the tin compounds, however. Suitable organotin compounds are, for example, the 1,3-dicarbonyl compounds of bivalent or tetravalent tin, for example, the acetylacetonates such as di(n-butyl)tin(IV) di(acetylacetonate), di(n-octyl)tin(IV) di(acetylacetonate), (n-octyl)(n-butyl)tin(IV) di(acetylacetonate); the dialkyl tin(IV) dicarboxylates, for example, di-n-butyltin dilaurate, di-n-butyltin maleate, di-n-butyltin diacetate, di-n-octyltin dilaurate, di-n-octyltin diacetate, or the corresponding dialkoxylates, for example, di-n-butyltin dimethoxide; oxides of tetravalent tin, for example, dialkyltin oxides, such as, for example, di-n-butyltin oxide and di-n-octyltin oxide; and the tin(II) carboxylates such as tin(II) octoate or tin(II) phenolate. Suitable furthermore are tin compounds of ethyl silicate, dimethyl maleate, diethyl maleate, dioctyl maleate, dimethyl phthalate, diethyl phthalate, dioctyl phthalate, such as, for example, di(n-butyl)tin(IV) dimethyl maleate), di(n-butyl)tin(IV) di(butyl maleate), di(n-octyl)tin(IV) di(methyl maleate), di(n-octyl)tin(IV) di(butyl maleate), di(n-octyl)tin(IV) di(isooctyl maleate); and di(n-butyl)tin(IV) sulfide, (n-butyl)2Sn(SCH2COO), (n-octyl)2Sn(SCH2COO), (n-octyl)2Sn(SCH2CH2COO), (n-octyl)2Sn(SCH2CH2COOCH2CH2OCOCH2S), (n-butyl)2-Sn(SCH2COO-i-C8H17)2, (n-octyl)2Sn(SCH2COO-i-C8H17)2, and (n-octyl)2Sn(SCH2COO-n-C8H17)2. Preferably, the tin compound is selected from 1,3-dicarbonyl compounds of bivalent or tetravalent tin, the dialkyltin(IV) dicarboxylates, the dialkyltin(IV) dialkoxylates, the dialkyltin(IV) oxides, the tin(II) carboxylates, and mixtures thereof. Particularly preferably, the tin compound is a dialkyltin(IV) dicarboxylate, particularly di-n-butyltin dilaurate or di-n-octyltin dilaurate. The curable compositions contain the tin compound preferably in an amount of 0.01 to 2% by weight, preferably in an amount of 0.05 to 2% by weight, particularly preferably in an amount of 0.1 to 0.5% by weight, based in each case on the total weight of the composition. If a mixture of a number of tin compounds is used, the quantitative data naturally refer to the total amount of tin compounds in the composition. The compositions of the invention crosslink in the presence of moisture and in so doing cure with the formation of Si—O—Si bonds. Adjusting the molar ratio of the aminosilane and tin compound in the range of 1:1 to 50:1 assures that the curable composition, on the one hand, has very high storage stability and, on the other, cures reliably and at a sufficient rate after application in the presence of atmospheric moisture even at room temperature (23° C.). The molar ratio of the aminosilane to the tin compound is preferably 10:1 to 40:1, particularly preferably 20:1 to 35:1. The curable compositions can contain, apart from the obligatory components, one or more components that can be used to influence specific properties of the curable composition and/or the cured product selectively. These other components can be selected, for example, from the group comprising plasticizers, stabilizers, antioxidants, fillers, reactive diluents, drying agents, adhesion promoters, UV stabilizers, rheological aids, and/or solvents. In this case, particular importance is attached to plasticizers, fillers, and stabilizers, comprising antioxidants and UV stabilizers. Preferably, the curable compositions therefore contain at least one further component. It is conceivable that the viscosity of the curable composition is too high for certain applications. It can then be reduced in a simple and expedient way usually by using a reactive diluent, without any signs of demixing (e.g., plasticizer migration) occurring in the cured mass. Preferably, the reactive diluent has at least one functional group which after application reacts, e.g., with moisture or atmospheric oxygen. Examples of groups of this type are silyl groups, isocyanate groups, vinylically unsaturated groups, and polyunsaturated systems. All compounds that can be mixed with the other components with a reduction in viscosity and have at least one group reactive with the polymer can be used as reactive diluents. The viscosity of the reactive diluent is preferably less than 20,000 mPas, particularly preferably about 0.1 to 6000 mPas, very particularly preferably 1 to 1000 mPas (Brookfield RVT, 23° C., spindle 7, 10 rpm). The following substances, for example, can be used as reactive diluents: polyalkylene glycols reacted with isocyanatosilanes (e.g., Synalox 100-50B, DOW), carbamatopropyltrimethoxysilane, alkyltrimethoxysilane, alkyltriethoxysilane, such as methyltrimethoxysilane, methyltriethoxysilane, and vinyltrimethoxysilane (XL 10, Wacker), vinyltriethoxysilane, phenyltrimethoxysilane, phenyltriethoxysilane, octyltrimethoxysilane, tetraethoxysilane, vinyldimethoxymethylsilane (XL12, Wacker), vinyltriethoxysilane (GF56, Wacker), vinyltriacetoxysilane (GF62, Wacker), isooctyltrimethoxysilane (IO Trimethoxy), isooctyltriethoxysilane (IO Triethoxy, Wacker), N-trimethoxysilylmethyl-O-methyl carbamate (XL63, Wacker), N-dimethoxy(methyl)silylmethyl-O-methyl carbamate (XL65, Wacker), hexadecyltrimethoxysilane, 3-octanoylthio-1-propyltriethoxysilane, and partial hydrolysates of said compounds. Further, the following polymers from Kaneka Corp. can also be used as reactive diluents: MS S203H, MS S303H, MS SAT 010, and MS SAX 350. Silane-modified polyethers which derive, e.g., from the reaction of isocyanatosilane with Synalox types can likewise be used. Polymers that can be prepared from an organic framework by grafting with a vinylsilane or by reacting polyol, polyisocyanate, and alkoxysilane can be used, furthermore, as reactive diluents. A polyol is understood to be a compound that may contain one or more OH groups in the molecule. The OH groups can be both primary and secondary. Suitable aliphatic alcohols include, for example, ethylene glycol, propylene glycol, and higher glycols, as well as other polyfunctional alcohols. The polyols can contain in addition other functional groups such as. e.g., esters, carbonates, or amides. To prepare the preferred reactive diluents, the corresponding polyol component is reacted in each case with an at least difunctional isocyanate. Any isocyanate having at least two isocyanate groups may basically be used as the at least difunctional isocyanate, but within the scope of the present invention, compounds with two to four isocyanate groups, particularly with two isocyanate groups, are generally preferred. Preferably, the compound present as the reactive diluent has at least one alkoxysilyl group, whereby of the alkoxysilyl groups, the di- and trialkoxysilyl groups are preferred. Suitable as polyisocyanates for the preparation of a reactive diluent are, for example, ethylene diisocyanate, 1,4-tetramethylene diisocyanate, 1,4-tetramethoxybutane diisocyanate, 1,6-hexamethylene diisocyanate (HDI), cyclobutane-1,3-diisocyanate, cyclohexane-1,3 and -1,4 diisocyanate, bis(2-isocyanatoethyl) fumarate, as well as mixtures of two or more thereof, 1-isocyanato-3,3,5-trimethyl-5-isocyanatomethyl cyclohexane (isophorone diisocyanate, IPDI), 2,4- and 2,6-hexahydrotoluylene diisocyanate, hexahydro-1,3- or -1,4-phenylene diisocyanate, benzidine diisocyanate, naphthalene-1,5-diisocyanate, 1,6-diisocyanato-2,2,4-trimethylhexane, 1,6-diisocyanato-2,4,4-trimethylhexane, xylylene diisocyanate (XDI), tetramethylxylylene diisocyanate (TMXDI), 1,3- and 1,4-phenylene diisocyanate, 2,4- or 2,6-toluylene diisocyanate (TDI), 2,4′-diphenylmethane diisocyanate, 2,2′-diphenylmethane diisocyanate, or 4,4′-diphenylmethane diisocyanate (MDI), or the partially or completely hydrogenated cycloalkyl derivatives thereof, for example, completely hydrogenated MDI (H12-MDI), alkyl-substituted diphenylmethane diisocyanates, for example, mono-, di-, tri-, or tetraalkyl diphenylmethane diisocyanate and the partially or completely hydrogenated cycloalkyl derivatives thereof, 4,4′-diisocyanatophenyl perfluoroethane, phthalic acid bis-isocyanatoethyl ester, 1-chloromethylphenyl-2,4- or -2,6-diisocyanate, 1-bromomethylphenyl-2,4- or -2,6-diisocyanate, 3,3-bis-chloromethyl ether-4,4′-diphenyl diisocyanate, sulfur-containing diisocyanates, as can be obtained by reacting 2 mol of diisocyanate with 1 mol of thiodiglycol or dihydroxydihexyl sulfide, the di- and triisocyanates of dimer and trimer fatty acids, or mixtures of two or more of the aforesaid diisocyanates. Trivalent or higher-valent isocyanates, as can be obtained, for example, by oligomerization of diisocyanates, particularly by oligomerization of the aforesaid isocyanates, can also be used as polyisocyanates. Examples of such trivalent and higher-valent polyisocyanates are the triisocyanurates of HDI or IPDI or mixtures thereof or mixed triisocyanurates thereof, as well as polyphenylmethylene polyisocyanate, as can be obtained by phosgenation of aniline-formaldehyde condensation products. Solvents and/or plasticizers can be used, in addition to or instead of a reactive diluent, for reducing the viscosity of the curable composition. Suitable as solvents are aliphatic or aromatic hydrocarbons, halogenated hydrocarbons, ketones, ethers, esters, ester alcohols, keto alcohols, keto ethers, keto esters, and ether esters. The composition described herein furthermore can contain hydrophilic plasticizers. These are used to improve the moisture absorption and thereby to improve the reactivity at low temperatures. Suitable as plasticizers are, for example, esters of abietic acid, adipic acid esters, azelaic acid esters, benzoic acid esters, butyric acid esters, acetic acid esters, esters of higher fatty acids having approximately 8 to approximately 44 carbon atoms, epoxidized fatty acids, fatty acid esters and fats, glycolic acid esters, phosphoric acid esters, phthalic acid esters, linear or branched alcohols containing 1 to 12 carbon atoms, propionic acid esters, sebacic acid esters, sulfonic acid esters, thiobutyric acid esters, trimellitic acid esters, citric acid esters, and esters based on nitrocellulose and polyvinyl acetate, as well as mixtures of two or more thereof. For example, of the phthalic acid esters, dioctyl phthalate, dibutyl phthalate, diisoundecyl phthalate, or butylbenzyl phthalate is suitable, and of the adipates, dioctyl adipate, diisodecyl adipate, diisodecyl succinate, dibutyl sebacate, or butyl oleate. Likewise suitable as plasticizers are the pure or mixed ethers of monofunctional, linear or branched C4-16 alcohols or mixtures of two or more different ethers of such alcohols, for example, dioctyl ether (obtainable as Cetiol OE, Cognis Deutschland GmbH, Düsseldorf). Endcapped polyethylene glycols are suitable further as plasticizers, for example, polyethylene or polypropylene glycol di-C1-4-alkyl ethers, particularly the dimethyl or diethyl ethers of diethylene glycol or dipropylene glycol, and mixtures of two or more thereof. Particularly preferred as plasticizers, however, are endcapped polyethylene glycols, such as polyethylene or polypropylene glycol dialkyl ethers, where the alkyl group has up to four C atoms, and particularly the dimethyl and diethyl ethers of diethylene glycol and dipropylene glycol. An acceptable curing is achieved in particular with dimethyldiethylene glycol also under less favorable application conditions (low humidity, low temperature). Reference is made to the relevant technical chemistry literature for further details on plasticizers. Likewise suitable as plasticizers within the scope of the present invention are diurethanes, which can be prepared, for example, by reacting diols, having OH end groups, with monofunctional isocyanates, by selecting the stoichiometry such that substantially all free OH groups react. Optionally excess isocyanate can then be removed from the reaction mixture, for example, by distillation. A further method for preparing diurethanes consists of reacting monofunctional alcohols with diisocyanates, whereby all NCO groups are reacted if possible. Preferably, the curable composition has at least one plasticizer, particularly a polydimethylsiloxane. The curable compositions contain the plasticizer preferably in an amount of 1 to 50% by weight, preferably in an amount of 10 to 40% by weight, particularly preferably in an amount of 20 to 30% by weight, based in each case on the total weight of the composition. If a mixture of a number of plasticizers is used, the quantitative data naturally refer to the total amount of plasticizers in the composition. The composition described herein can contain in addition up to about 20% by weight of conventional adhesion promoters (tackifiers). Suitable as adhesion promoters are, for example, resins, terpene oligomers, coumarone/indene resins, aliphatic petrochemical resins, and modified phenol resins. Suitable within the context of the present invention are, for example, hydrocarbon resins, as can be obtained by polymerization of terpenes, primarily α- or β-pinene, dipentene, or limonene. These monomers are generally polymerized cationically with initiation using Friedel-Crafts catalysts. The terpene resins also include, for example, copolymers of terpenes and other monomers, for example, styrene, α-methylstyrene, isoprene, and the like. The aforesaid resins are used, for example, as adhesion promoters for contact adhesives and coating materials. Likewise suitable are terpene-phenol resins, which are prepared by the acid-catalyzed addition of phenols to terpenes or rosin. Terpene-phenol resins are soluble in most organic solvents and oils and miscible with other resins, waxes, and caoutchouc. Likewise suitable as an additive in the aforesaid sense within the context of the present invention are the rosin resins and derivatives thereof, for example, the esters thereof. Because particularly due to the presence of the aminosilane the curable compositions generally already exhibit very good adhesion to very many materials, however, the addition of other adhesion promoters can often be omitted. Preferably, the curable composition contains at least one stabilizer, selected from antioxidants, UV stabilizers, and drying agents. All conventional antioxidants may be used as antioxidants. They are preferably present up to about 7% by weight, particularly up to about 5% by weight. The composition herein can contain UV stabilizers, which are preferably used up to about 2% by weight, preferably about 1% by weight. The so-called hindered amine light stabilizers (HALS) are particularly suitable as UV stabilizers. It is preferred within the context of the present invention if a UV stabilizer is employed, which carries a silyl group and is incorporated into the end product during crosslinking or curing. The products Lowilite 75 and Lowilite 77 (Great Lakes, USA) are particularly suitable for this purpose. Further, benzotriazoles, benzophenones, benzoates, cyanoacrylates, acrylates, sterically hindered phenols, phosphorus, and/or sulfur can also be added. It is often useful to stabilize the compositions in regard to penetrating moisture by means of drying agents in order to increase the storability (shelf life) still further. Such an improvement in storability can be achieved, for example, by using drying agents. All compounds that react with water with the formation of a group inert to the reactive groups present in the preparation are suitable as drying agents and thereby undergo the smallest possible changes in their molecular weight. Furthermore, the reactivity of the drying agents to moisture penetrating into the preparation must be higher than the reactivity of the groups of the silyl group-bearing polymer of the invention present in the preparation Isocyanates, for example, are suitable as drying agents. Advantageously, however, silanes are used as drying agents. For example, vinylsilanes such as 3-vinylpropyltriethoxysilane, oxime silanes such as methyl-O,O′,O″-butan-2-one-trioximosilane or O,O′,O″,O″′-butan-2-one-tetraoximosilane (CAS Nos. 022984-54-9 and 034206-40-1) or benzamidosilanes such as bis(N-methylbenzamido)methylethoxysilane (CAS No. 16230-35-6) or carbamatosilanes such as carbamatomethyltrimethoxysilane. The use of methyl-, ethyl-, or vinyltrimethoxysilane, tetramethyl- or tetraethylethoxysilane is also possible, however. Vinyltrimethoxysilane and tetraethoxysilane are particularly preferred in terms of cost and efficiency. Likewise suitable as drying agents are the aforesaid reactive diluents, provided they have a molecular weight (Mn) of less than about 5000 g/mol and have end groups whose reactivity to penetrated moisture is at least as high as, preferably higher than, the reactivity of the reactive groups of the polymer used according to the invention. Lastly, alkyl orthoformates or alkyl orthoacetates can also be used as drying agents, for example, methyl or ethyl orthoformate or methyl or ethyl orthoacetate. The compositions generally contain about 0 to about 6% by weight of drying agent. The composition described herein can contain fillers in addition. Suitable here are, for example, chalk, lime powder, precipitated and/or pyrogenic silicic acid, zeolites, bentonites, magnesium carbonate, kieselguhr, alumina, clay, tallow, titanium oxide, iron oxide, zinc oxide, sand, quartz, flint, mica, glass powder, and other ground mineral substances. Organic fillers can also be used, furthermore, particularly carbon black, graphite, wood fibers, wood flour, sawdust, cellulose, cotton, pulp, cotton, wood chips, chopped straw, and chaff. Further, short fibers such as glass fibers, glass filament, polyacrylonitrile, carbon fibers, Kevlar fibers, or polyethylene fibers as well can also be added. Aluminum powder is likewise suitable as a filler. The pyrogenic and/or precipitated silicic acids advantageously have a BET surface area of 10 to 90 m2/g. When they are used, they do not cause any additional increase in the viscosity of the composition of the invention, but contribute to strengthening the cured composition. It is likewise conceivable to use pyrogenic and/or precipitated silicic acids with a higher BET surface area, advantageously with 100 to 250 m2/g, particularly 110 to 170 m2/g, as a filler. Because of the higher BET surface area, the same effect, e.g., strengthening of the cured preparation, can be achieved at a smaller weight proportion of silicic acid. Further substances can thus be used to improve the composition described herein in terms of other requirements. Suitable further as fillers are hollow spheres having a mineral shell or a plastic shell. These can be, for example, hollow glass spheres which are obtainable commercially under the trade names Glass Bubbles®. Plastic-based hollow spheres, e.g., Expancel® or Dualite®, are described, for example, in EP 0 520 426 B1. They are made up of inorganic or organic substances and each have a diameter of 1 mm or less, preferably 500 μm or less. Fillers that impart thixotropy to the preparations are preferred for many applications. Such fillers are also described as rheological adjuvants, e.g., hydrogenated castor oil, fatty acid amides, or swellable plastics such as PVC. In order to be readily squeezable out of a suitable dispensing device (e.g., a tube), such preparations possess a viscosity from 3000 to 15,000, preferably 40,000 to 80,000 mPas, or even 50,000 to 60,000 mPas. The fillers are preferably used in an amount of 1 to 80% by weight, particularly preferably 2 to 20% by weight, and very particularly preferably 5 to 10% by weight, based in each case on the total weight of the composition. Of course, mixtures of a number of fillers can also be used. In this case, the quantitative data naturally refer to the total amount of filler in the composition. The subject matter of the invention is furthermore a method for preparing the compositions of the invention. The preparation of the curable composition can take place by simple mixing of the polyorganosiloxane, which has at least one hydroxy group bound to a silicon atom, the silane of the formula (1), the aminosilane, the tin compound, and optionally the other ingredients. This can take place in suitable dispersing units, e.g., a high-speed mixer. In this case, preferably, care is taken that the mixture does not come into contact with moisture as far as possible, which could lead to an undesirable premature curing. Suitable measures are sufficiently known and comprise, for example, working in an inert atmosphere, possibly under a protective gas, and drying/heating of individual components before they are added. A preferred production method comprises mixing the polyorganosiloxane, which has at least one hydroxy group bound to a silicon atom, and the silane of the formula (1) in a first step, whereby this takes place in the presence of the entire amount of the aminosilane or a part thereof and optionally at least one plasticizer, in a second step adding the remaining portion of the aminosilane and optionally other ingredients and mixing all ingredients, and in a third step adding the tin compound and mixing it with the other components. The subject matter of the invention, moreover, is the use of the compositions of the invention as an adhesive or sealing or coating material. The composition can be used, for example, as an adhesive, sealant, surfacer, and for the production of molded parts. A further field of application for the compositions is the use as a plugging compound, hole filler, or crack filler. The use as a sealant is preferred. The compositions are suitable, inter alia, for bonding plastics, metals, glass, ceramic, wood, wood-based materials, paper, paper-based materials, rubber, and textiles, for gluing floors, and for sealing building elements, windows, wall and floor coverings, and joints in general. In this case, the materials can be bonded to themselves or as desired to one another. The following examples serve to explain the invention, but the invention is not limited thereto. EXAMPLES Example 1 The comparison compositions VB1 and VB3 and composition B2 of the invention were prepared by mixing the raw materials listed in Table 1. All three formulations are based on the same raw materials but differ in the quantitative ratio of the aminosilane to the tin compound. Only composition B2 contains these components in the ratio required according to the invention.

All tests were carried out with the freshly formulated composition and after 4 and 12 weeks of aging at 40° C./80% relative humidity. The results for the comparison formulation VB1 are presented in Table 2, and the results for the formulation of the invention B2 in Table 3. The comparison formulation VB3 already crosslinks when the raw materials are mixed, so that no mechanical properties could be determined. A comparison of the results for the comparison formulation VB1 and formulation of the invention B2 shows that no workable curing behavior can be achieved for the comparison formulation after storage, and the mechanical properties of the cured product are insufficient. The formulation can no longer be cured at all even after 12 weeks of aging under the given conditions. The formulation therefore does not have an adequate storage stability.
