liquid Polyurethane waterproof membrane coating materials Weifang Fuhua

The product is flexible waterproof coating with isocyanate and Polyether polyol as mail raw material plus some additives and fillers by polyaddition reaction. By coating it on the base and through the polyurethane prepolymerization reaction between NCO Terminal group and the moisture in the air, it form into a layer of rubber waterproof film on the base surface, which are toughened, flexible, seamless.
