Abstract
The present invention provides stable, high solids, aqueous emulsions of high viscosity masked (poly)isocyanates, water, surface active agents, and, optionally, thickening water-soluble polymers. The emulsions of the present invention are formulated in as little as 20 parts by weight water or less. The present invention further provides processes for forming such emulsions.
