Abstract
High solids, solvent-based resin composition comprises novel chain-extendable, crosslinkable urethane modified polyhydroxy oligomers, crosslinking agent and, preferably, catalyst(s). The composition cures at elevated temperature to provide a coating on a substrate, such as steel, which is highly resistant to corrosion, humidity and solvents and provides corrosion protection for the substrate. The novel oligomers can be the reaction product of a polyol with a half-blocked diisocyanate, wherein said polyol comprises three or more hydroxy, and the half-blocked diisocyanate comprises the reaction product of an organic diisocyanate with approximately one molar equivalent of a monofunctional blocking agent.
