MS waterproof coating is specially designed for building waterproof products, non-toxic, non-corrosive, high and low temperature resistance, and has excellent weather resistance, aging resistance, uv resistance, excellent bonding performance, and good compatibility with other materials, more durable than traditional polyurethane coating waterproof effect.
Applications
1、Used for waterproof and anticorrosive metal surface, such as: building steel structure, aluminum alloy profiles, color steel plate, color steel tile surface;
2、The building roof waterproof, indoor toilet waterproof
