Coating compositions and methods with polyfunctional carbamate salt

Abstract

A latent base catalyst and compositions and methods involving latent base-catalyzed Michael addition reaction are described herein. The described latent base catalyst is a substituted carbamate salt. The compositions described herein are derived from a Michael addition reaction and provide coatings, including primer coatings and direct- to-metal coatings, which have optimal potlife and cure response, and also demonstrate optimal adhesion, corrosion resistance, and weatherability when applied to a substrate and cured. 20 26 23 80 90 24 S ep 2 02 6 A B S T R A C T 2 0 2 6 2 3 8 0 9 0 2 4 2 0 2 6 S e p a n d c u r e d .
