ABSTRACT:
Resin composition suitable for high solids, solvent-based coating composition comprises chain-extendable, crosslinkable polyol of molecular weight about 100 to 1000, having at least three hydroxyl groups, chain-extendable diblocked diisocyanate diurea oligomer of molecular weight about 200 to 1500, comprising the reaction product of a half-blocked diisocyanate with diamine, crosslinking agent reactive with the hydroxy functionality of the polyol and substantially unreactive with the de-blocked isocyanate functionality of said diblocked diisocyanate diurea oligomer, and, preferably, catalyst(s). The composition cures at elevated temperature to provide a coating on a substrate, such as steel, which coating is highly resistant to corrosion, humidity and solvents and provides corrosion protection for the substrate. The half-blocked diisocyanate is preferably the reaction product of an organic diisocyante with monofunctional blocking agent. The polyol is preferably the reaction product of a diol of molecular weight about 60 to 500 with a diepoxide of molecular weight about 100 to 1000 such as bisphenol A epichlorohydrin epoxy resin, hydantoin epoxy resin and the like.
