DUAL-CURE COMPOSITIONS USEFUL FOR COATING METAL SUBSTRATES AND PROCESSES USING THE COMPOSITIONS

摘要

A film-forming composition capable of undergoing dual cure, comprising: (1) a resin component comprising at least one polyepoxide; and (2) a radiation-curable diluent comprising a reaction product of a composition comprising: (a) a partially capped polyisocyanate; and (b) an ethylenically unsaturated monomer having active hydrogen functional groups capable of reacting with isocyanate groups. Also provided are processes for improving corrosion resistance of a metal substrate using the above composition.
