摘要: Disclosed is a coating composition suitable for coating metal pipe, especially the interior of pipe. The coating composition comprises a blend of one or more polyether polyols and a flexibilizing stearically hindered amine-initiated polyether polyol and a multi-isocyanate curing agent. The curing composition optionally may contain an organic solvent and inert particulate filler. The coating composition cures within about 1 to 3 minutes after application and preferably is spray applied. The coating composition possesses adequate flexibility to pass a 15% ring deflection test.
