Abstract
A composition containing an unblocked monomeric diisocyanate finely dispersed an aqueous dispersion of at least one organic polyhydroxy compound. The composition may be used to prepare aqueously disperse two component polyurethane coatings where the diisocyanate functions as a curing agent and the polyhydroxy compound serves as a binder agent. In the composition, the ratio of hydroxyl groups in the polyhydroxy compound to the isocyanate groups in the diisocyanate is 0 5:1 to 5:1. The composition may be used to apply polyurethane coatings to substrates.
