A RESIN FOR USE IN A COATING COMPOSITION

摘要

A coating system comprises a substrate and a cured film disposed on the substrate and formed from a coating composition. The coating composition comprises a solvent component and a resin. The resin comprises a reaction product of a polyolefin and an oligomer or polymer. The polyolefin, different from the oligomer or polymer, has a functional group that is reactive with the oligomer or polymer and the functional group is selected from acrylate, methacrylate, carboxyl, hydroxyl, epoxide, anhydride and isocyanate functional groups. The oligomer or polymer and the polyolefin are at least partially immiscible in solution at ambient temperature. The oligomer or polymer is grafted with the polyolefin to form the resin.
