摘要：
A coating composition contains an organic polyol, a polyepoxide, a blocked polyisocyanate crosslinking agent, and a phenolic resin. The coating composition also can be formulated as a two package coating composition with a free polyisocyanate crosslinking agent. The composition is flexible, having an elongation of at least 10 percent when cured. This coating composition is particularly suitable as a primer in preparing substrates with a multilayer coating having good flexibility.
