Abstract:
1. A method of coating a substrate to provide a transparent, abrasion-resistant coating, the method comprising the steps of providing a coating composition comprising: a) the hydrolysis product of an epoxy-functional alkoxy silane, b) a curing agent for polymerizing epoxy compounds, the curing agent comprising a cationic photoinitiator, c) an ethylenically unsaturated monomer and photoactivated free-radical initiator therefore, and d) a viscosity-reducing amount up to 50% by weight, solids basis, of an unhydrolyzed epoxy-functional alkoxy silane, and applying the composition to the substrate in order to form a transparent, abrasion-resistant coating.
