Patent ID: 7928160

Claim:
A coating composition comprising: (a) polyurea 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 and the isocyanate-functional component and the amine-functional component can be applied to a substrate at a volume mixing ratio of 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 an isocyanate-functional polyisocyanate prepolymer which is a reaction product of a polyisocyanate and a polyol, and wherein the amine-functional component is selected from aliphatic polyamines, mono- and poly-acrylate and methacrylate modified amines, polyaspartic ester-based polyamines, and/or polyoxyalkylene amines; (b) polyurethane; and (c) a flame retardant component.
