摘要：
A coating composition that forms a flexible finish and is used primarily as a clear finish over a colored or pigmented finish that are applied to flexible substrates of automobile and truck bodies; the composition contains as the film forming binder (1) a branched aliphatic polyester urethane which is the reaction product of a polyisocyanate and a branched aliphatic polyester and (2) preferably a methylated and butylated melamine formaldehyde crosslinking agent.
