Also known as polyurethane film waterproof material, polyurethane waterproof coating is a type of high-molecular waterproof coating with polyurethane resin as the main film-forming component. It is formulated by mixing curing agents containing isocyanate groups with other auxiliary agents in specific proportions, free of additives such as coal tar and asphalt. As a solvent-free, single-component eco-friendly waterproof coating applied in liquid form, it cures upon contact with moisture in ambient air to form a seamless, robust and tough integrated waterproof film on the substrate surface.
