ABSTRACT:
A crosslinked and chain extended urethane-epoxy copolymer coating with high performance properties typical of two part urethane solution coatings results from cure at ambient temperatures (e.g. 70.degree. F.) when the two aqueous systems are merely mixed, stirred and spread at the site. One aqueous system is a dispersion of polyepoxides. The other aqueous system is a primary amine-terminated urethane oligomer in which no less than about 25% and no more than about 40% of the amine functionality is substituted by a salt of a volatile acid which aids dispersion of the oligomer. Minimal organic solvent is present, and as the acid evaporates, the primary amine is restored for linking with the epoxy groups.
