ABSTRACT:
Disclosed is an improved method for coating a substrate with a film of a coating composition rapidly curable at room temperature in the presence of a vaporous tertiary-amine catalyst. The pot life of the coating composition is substantially increased without deleterious loss of properties of the ultimately cured film wherein the coating composition comprises three components. The first component is a phenol-functional condensation product of (a) a phenol-aldehyde reaction product bearing a plurality of methylol and phenol groups, and (b) a polyol, polycarboxylic acid, or polyepoxide, wherein the condensation product is reacted with a selective transmethylolating agent for substantially transforming residual methylol groups into non-active hydrogen groups. The second component is a multi-isocyanate cross-linking agent and the third component is an organic solvent. The coating composition is applied to a substrate and cured by exposure of the coated substrate to a vaporous tertiary amine catalyst.
