Abstract
Abstract A coating composition 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 epoxy compound; wherein the polyesterurethane is formed by reacting a hydroxy functional polyester with a hydroxy containing carboxylic acid and an organic polyisocyanate and the multifunctional epoxy resin is an aliphatic, cycloaliphatic or aromatic epoxy resin; coated parts, laminates and composite structures made with the coating composition are also part of the invention.
