Abstract
An abrasion-resistant coating composition for use on transparent plastic substrates and the like is formed from a first component derived by partial hydrolysis from a hydrolyzable epoxysilane and a second component comprising the reaction product of a non-silane-based aliphatic polyamine and a ketone or aldehyde. The two components are mixed to allow regenerated amino groups of the first component to react with the epoxy groups of the second component to form a partially polymerized mixture which is diluted with a solvent and applied to the substrate and heated to complete the curing process.
