ABSTRACT:
Novel solvent-based thermosetting composition comprising (a) hydroxy functional epoxy ester resin of number average molecular weight (Mn) between about 1,000 and about 5,000, being formed by reaction of diepoxide, which has been chain extended with diphenol and dicarboxylic acid, with hydroxy functional secondary amine in chain terminating reaction, in approximately 1:1 equivalent ratio: and (b) polyfunctional, hydroxyreactive crosslinking agent, for example, aminoplast crosslinking agent and blocked polyisocyanate crosslinking agent comprising isocyanate groups blocked by reaction with an active hydrogen bearing blocking agent. The coating composition may be formulated as a primer sprayable with conventional spraying equipment.
