COMPOSITIONS AND METHODS OF PROMOTING ADHESION BETWEEN A SUBSTRATE AND A POLYUREA/POLYURETHANE COATING

摘要

The present invention is directed to a compositions comprising polyurea an adhesion promoter wherein the adhesion promoter comprises an adduct of an aminosilane and a material chosen from an acrylate, a methacrylate, a lactone, and mixtures thereof. The present invention is also directed to methods of applying the compositions to improve the adhesion of a polyurea or polyurea and polyurethane coating to a substrate.
