Coating composition of polyesterurethane and polyisocyanate crosslinking agent

摘要

A coating compostion particularly useful in for forming exterior finishes on the exterior of vehicle parts, the binder of the composition which is in an organic liquid carrier is a polyesterurethane and a multifunctional organic polyisocyanate crosslinking agent; wherein the polyesterurethane is formed by reacting a hydroxy functional polyester with a hydroxy containing carboxylic acid and an organic polyisocyanate and the multifunctional organic polyisocyanate crosslinking agent has at least three reactive isocyanate groups and may be blocked with a blocking agent; coated parts, laminates and composite structures made with the coating composition are also part of the invention.
