WJG-323 Environmentally friendly white one-component polyurethane waterproof coating
WJG-323 environmentally friendly white one-component polyurethane waterproof coating is made from isocyanate and polyether polyol as main raw materials, with various auxiliaries and fillers processed and polymerized. When used, it is coated on the waterproof base layer. After the -NCO end group in the polyurethane prepolymer contacts with moisture in the air, a chemical reaction occurs, forming a seamless, strongly bonded, elastic, non-toxic, environmentally friendly, and tough rubber waterproof coating on the surface of the base layer.
