Polyurethane waterproof coating because of its excellent physical and chemical properties, 951 polyurethane waterproof coating, is now widely used in water engineering. Among the most widely used tar-based polyurethane. But with social development and people's living standards improve, waterborne polyurethane waterproof coating, people began to pay more attention to environmental protection and their own health. Coal tar contains a large number of aliphatic and aromatic compounds, has a strong irritating odor, which anthracene, naphthalene and other ingredients harmful to human health.

Beijing Municipal Construction Committee also encourages the development and recommended six kinds of environment-friendly polyurethane waterproof coating; (1) single-component polyurethane waterproof coating; (2) color polyurethane waterproof coating; (3) an inorganic filler polyurethane waterproof coating; (4) water curing polyurethane waterproof coating; (5) petroleum pitch-based polyurethane waterproof coating; (6) petroleum resin-based polyurethane waterproof coating; polyurethane waterproof coating is the reaction of isocyanates, polyether by addition polymerization containing isocyanate prepolymer , together with the catalyst, anhydrous additive, anhydrous fillers, solvents, etc., by mixing processing into single-component polyurethane coatings. Currently, waterproof material on the market varied, with domestic and imported, joint venture; there are high-end, mid-range and low-end. Home improvement waterproof material used is bitumen polyurethane waterproof coatings, environmentally friendly polyurethane waterproof coatings and polymer cement waterproof coating.
