1. A coating composition formed from components comprising: (a) at least one polysiloxane comprising at least one reactive functional group, the polysiloxane comprising at least one of the following structural units (I): R 1 n R 2 m SiO (4-n-m)/ 2 ( I ) wherein each R 1, which may be identical or different, represents H, OH, a monovalent hydrocarbon group or a monovalent siloxane group; each R 2, which may be identical or different, represents a group comprising at least one reactive functional group, wherein m and n fulfill the requirements of 0<n<4, 0<m<4 and 2&lE;(m&plus;n)<4; (b) at least one reactant comprising at least one functional group that is reactive with the reactive functional group of the polysiloxane (a); and (c) at least one boron-containing compound selected from boric acid, boric acid equivalents, and mixtures thereof, wherein each component is different.
