Abstract:
1. A topcoat for a chemical warfare agent resistant coating (CARC) having a modifier in the form of a functionalized hyperbranched polymer (HBP), said topcoat comprising: a one-component or two-component polymer paint or coating; and an additive comprising a functionalized hyperbranched polymer (HBP) having a polyfunctional scaffold in the form of a hyperbranched polymer (HBP); and at least one buoy group coupled to said polyfunctional scaffold, said buoy group containing at least one long aliphatic chain end selected from a group consisting of an ester or amide of palmitic acid (HOCOC wherein the long aliphatic chain end functionalization of said HBP are crystalline and reduce surface spread of a chemical warfare agent across the surface of said paint or coating; and wherein said additive to enhances the resistance and repellency of said paint or coating to chemical warfare agents.
