摘要：

A UV-curable coating for plastics that is abrasion resistant and weatherable is described. The coating consists of colloidal silica functionalized with methacryloxypropyltrimethoxysilane (MAPTMS) in a matrix of acrylic monomers. The formulation employs diethoxyacetophenone (DEAP) as a photoinitiator and a sulfonated benzotriazole as a UV absorber. It has been found that the adhesion of the coating depends greatly on the type of acrylic monomers used and the application parameters. Transmission electron microscopy (TEM) analysis shows that improved adhesion is due to the formation of an interpenetrating layer between coating and substrate.
