The Railway & Bridge Special Polyurethane Waterproof Coating is made from isocyanate and polyether polyol primarily, by added in various additives and filler during a polymerization reacting process. At application, mix the two parts of the product by correct ratio and paint it onto the substrate. The NCO end group will react with the active hydroxy and amido within the polyurethane prepolymer, thus solidifies and forms strong adhesion between the substrate and the waterproof membrane.
