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 coating composition, comprising:
- a polysiloxane polymer comprising the reaction product of:
- (a) a hybrid copolymer comprising:
- (i) a first monomer comprising a hydroxy functional organoacrylate;
- and
- (ii) a second monomer comprising an organoalkoxysilane;
- and
- (b) a second material comprising an organoalkoxysilane,
- wherein said hybrid copolymer is present in an amount of 5 percent by weight to 40 percent by weight, and said second material is present in an amount of from 60 percent by weight to 95 percent by weight, the weight percents in each case being based on total weight of said hybrid copolymer and said second material.
