Abstract
The present invention is directed to an isocyanate-functional composition useful for forming a coating, adhesive, elastomer, or like article. Cure of the composition preferably involves trimerization of the isocyanate groups in the presence of an amino catalyst including a tertiary amine, an amine salt, and quaternary ammonium salts. The novel catalyst system used in achieving cure of the isocyanate-functional compound-containing liquid curable composition comprises an amino catalyst and an ortho-carboxylic acid ester.
