Patent ID: 8153197

Claim:
A process for providing an abrasion resistant coating on a formable plastic substrate, comprising: applying a coating composition to a formable plastic substrate, wherein the coating composition comprises, an aqueous-organic solvent mixture having hydrolysis products and partial condensates of at least one of an epoxy functional silane and a diol functional organopolysiloxane and at least one multifunctional crosslinker, wherein the multifunctional crosslinker comprises a silylated multifunctional anhydride, and wherein the at least one of the epoxy functional silane and the diol functional organopolysiloxane is present in a molar ratio to the multifunctional crosslinker from about 10:1 to 1:10, and an amount of water sufficient to hydrolyze the epoxy functional silane, the diol functional organopolysiloxane, and the silylated multifunctional crosslinker; curing the coating composition to produce a formable coated plastic substrate; and forming the formable coated plastic substrate into a desired shape by heating the formable coated plastic substrate until the formable coated plastic substrate softens and shaping the softened formable coated plastic substrate into the desired shape.
