Dow ISONATE™ 50 O,P` Pure MDI
Categories:	Fluid
Material Notes:	ISONATE™ 50 O,P` is a high ortho-para MDI designed for use in polyurethane adhesives, sealants, sports flooring, coatings, electrical encapsulants and flexible molded foams. ISONATE™ 50 O,P` offers formulators a slower reactivity and increased amorphous character for improved handling and longer pot life. In prepolymer formulation, it results in lower viscosity and improve shelf stability. 50% 4,4-diphenylmethane diisocyanate and 50% 2,4-diphenylmethane diisocyanate Information provided by Dow
