Polyurea coatings containing silane

摘要

The present invention is directed to a polyurea coating composition formed from an amine-functional component and an isocyanate-functional component. The amine-functional component can include an aspartic ester-based amine-functional resin and a blocked primary amine. The isocyanate-functional component can include a polyisocyanate having a functionality greater than 2.0 and an isocyanate equivalent weight of greater than 300, and a silane.
