COMPOSITION D'EMAIL POLYURETHANNIQUE A HAUTE TENEUR EN SOLIDES

摘要

A coating composition of a urethane polymer has film-forming constituents of an organic polyisocyanate, a low molecular weight hydroxyl-functional acrylic copolymer, and a low molecular weight hydroxyl-functional polyester based on branched-chain glycols. The composition can be applied at environmentally-acceptable solids levels and cured at ambient temperatures to form a durable film.
