REVESTIMENTOS TRATAVEIS POR PENETRACAO DE VAPOR PARA SUBSTRATOS DE SUPERFICIE POROSA

摘要

Disclosed is an improved method for coating a surface-porous substrate, e.g. an SMC substrate, with a film of curable coating composition and curing said film. The improvement comprises applying a film of the coating composition to the substrate wherein the coating composition comprises a phenol-functional compound and a multi-isocyanate curing agent therefor, and exposing the coated substrate to a vaporous tertiary amine catalyst to cure the applied film.
