Abstract
A curable composition comprising an epoxy-siloxane oligomer comprising as polymerized units one or more difunctional silane monomers of formula (1) and one or more trifunctional silane monomers of formula (2) in a mole ratio of 95:5 to 10:30 Si(R1)(R2)(Y1)2 (1)SiR3(Y2)3 (2) wherein R1, R2, and R3 are independently chosen from a C5-20-aliphatic group comprising an oxirane ring fused to an alicyclic ring, C1-20-alkyl, C6-30-aryl group, and a C5-20-aliphatic group having one or more heteroatoms; each Y1 and Y2 is independently chosen from halogen, C1-4-alkoxy, and —O—C1-4-acyl group; wherein at least one of R1, R2, and R3 is a C5-20-aliphatic group comprising an oxirane ring fused to an alicyclic ring; (b) organic particles having an average diameter of 50 to 250 nm; (c) a reactive carrier having one or more epoxy moieties or oxetane moieties; (d) a curing agent; and (e) one or more organic solvents, and methods of forming cured coatings using such compositions are described.
