Abstract

Aqueous emulsions comprise an organic isocyanate emulsified by a non ionic surfactant free of hydroxy amino or COOH gp. in water. Any org. isocyanate may be used pref. being an aromatic diisocyanate or an arom. isocyanate of higher functionalty. The emulsions are specifically claimed for binding polyurethane foam waste pref. in powder form into blocks. Other uses include adhesives and coatings to impart weathering resistance to wood, asbestos and concrete.
