pu waterproof coating material

DTPU-401 is a mono-component polyurethane waterproof coating produced by addition polymerization of polyether polyol with isocyanate and supplemented with certain additives and fillers. The -NCO end groups in the polyurethane prepolymer react with the moisture in the air and form a tough, flexible and seamless waterproof membrane on the coating base where the paint is applied to.
