Processing speed, manufacturing efficiency and uniform product quality have been the hallmarks of the coil coating industry. At Shamrock, we specialize in providing micronized waxes and fluoropolymers that enable coil coatings to maintain their integrity. Our slip aids and abrasion resistance additives protect your coatings by providing improved weatherability, durability and enhanced appearance in coatings applications as diverse as roof decking, auto exhaust systems, beverage can ends, appliances, venetian blinds, lighting fixtures and toys to name a few. We offer a full range of waxes and wax blends for water and solvent-based systems in particle sizes from submicron to 300 microns. Our additives can be used over aluminum or steel substrates and incorporated into the backer coat, primer or top coat.
Abrasion results from scuffing, scratching, wearing down, marring, or rubbing away. Products such as S-381N1, Taber Tiger 5512, Taber Plus 75, S-395 N2, FluoroSLIP 511, and SST-3D are recommended to provide abrasion resistance.
The ability of coating surfaces to resist to marking by metal. It is related to the hardness, the pigmentation, the coefficient of friction, and the topography of the coating. We recommend micronized wax products such as S-394N1, FluoroSLIP® 225, S-NAUBA 5021, and PTFE products such as SST-2 and SST-3.
Micronized PTFE powders improve the static, but not the dynamic coefficient of friction. PTFE is generally used in combination with other waxes such as carnauba or polyethylene. We offer blend of PTFE and waxes in different form: FluoroSLIP® 421, FluoroSLIP® 511, FluoroSLIP® 515, FluoroSLIP® 605. They improve the slip, gloss retention and present good abrasion resistance in coil coating application.
Wax additives such as Hydropel AF can change surface energy of coatings allowing for water repellency. Pre-wetted dispersions such as Hydrocer 145 or emulsions such as Hydrocer EE-95, Hydrocer EP-91 are recommended for their ease of use combined with enhancing gloss control, slip, and abrasion resistance.
The texture series has become the industry standard for high bake coil coatings. These polyolefins provide texture with a “suede-like” feel. Because of their intrinsic high melt viscosity, they will not lose their particle definition at metal temperatures as high as 500ºF. They are highly resistant to all solvents.
