Abstract
A two-package urethane forming coating composition comprises a hydroxyl-bearing polymer having ethylenic unsaturation dispersed in fugitive solvent; and a multi-isocyanate dispersed in fugitive solvent. The coating composition cures by heating with an in situ reaction of the hydroxyl-isocyanate reaction in combination with an in situ free-radical addition polymerization through the ethylenic unsaturation.
