Polyurea Spray Coating Protective Waterproof PU Paint Polyurethane
Polyurea stands protective material is a new generation product based on the latest third generation polyurea elastomer technology. It is composed of polymer, amino-terminated polyether, chain extender and various functional additives. The spray molding process is rapid. After the film is formed, it has the characteristics of high wear resistance, high elongation and medium resistance. It is used for sports stands, sewage treatment tanks, Soft pools, swimming pools, water parks, etc. provide a strong protective coating.
