Abstract:
1. A polyurea coating composition, the coating composition being formed from a reaction mixture comprising: an isocyanate-functional component and an amine-functional component wherein the ratio of equivalents of isocyanate groups to equivalents of amine groups is greater than 1 while the volume mixing ratio of the isocyanate-functional component to the amine-functional component is capable of being applied to a substrate at 1:1; wherein at least 1 percent by weight of the isocyanate-functional component comprises at least one polyisocyanate monomer and wherein the isocyanate-functional component further comprises the reaction product of a polyisocyanate and two or more polyols, and wherein the amine component comprises an aspartic ester-based amine-functional resin.
