ABSTRACT:
A crosslinked and chain extended urethane polymer coating with good performance properties typical of existing solvent borne solution coatings results from cure at ambient temperatures (e.g. 70.degree. F.). The 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 product lacquer dries.
