GB 2 type polyurethane waterproof coating
GB 2 type polyurethane waterproof coating
DTPU-403 (single component) and DTPU-404 (dual component) are high-performance environmentally friendly polyurethane coatings, which are environmentally friendly polymer waterproof coatings. The reaction is consolidated into a flexible, strong and durable waterproof coating. . The coating has excellent heat resistance, adhesion and acid and alkali resistance. The elastic high-strength coating film formed after construction on the road bridge can withstand long-term load movement of road and bridge, prevent damage caused by water seepage, steel corrosion, concrete carbonization, and greatly extend Road life.
