Abstract
A coating includes the reaction product of (a) a hybrid copolymer incorporating (i) a first monomer including a hydroxy-functional organoacrylate and (ii) a second monomer including an organoalkoxysilane and (b) a second material including an organofunctional alkoxysilane. The first monomer can be a hydroxy functional acrylate and/or a hydroxyalkylacrylate. The second monomer can be a trialkoxysilane. The second material can be a trialkoxysilane.

A method of making a coating composition, comprising the steps of:
- forming a hybrid copolymer comprising:
- (i) a first monomer comprising a hydroxy functional organoacrylate;
- and
- (ii) a second monomer comprising an organoalkoxy silane;
- reacting the hybrid copolymer with a second material comprising an organoalkoxysilane to form a polysiloxane polymer, and
- adding the polysiloxane polymer to a coating solution, wherein the coating solution is an aqueous solution comprising colloidal silica.
