Two-component polyurethane waterproof coating is a two-component reaction curing type synthetic polymer waterproof coating, with high tensile strength, elongation, and low temperature performance is good, the grass-roots stretching strong adaptability cracking or deformation characteristics. When you use the A, B two components by mixing, waterproof paint, stir well, brushing the required construction of the base surface, 951 polyurethane waterproof coating, after a few hours reaction curing to form a continuous, flexible waterproof coating layer. Polyurethane waterproof coating because of its excellent physical and chemical properties, has been widely used in water engineering. Among the most widely used tar-based polyurethane. But with social development and people's living standards improve, 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. Tar polyurethane environmental pollution has drawn increasing attention. 1997 Beijing Municipal Construction Committee expressed the hope that the company will develop environmentally friendly polyurethane waterproof coating; the end of 1998, has issued a "limit and eliminate tar polyurethane waterproof coating. 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; waterproof coating | long source | color polyurethane waterproof coating provided by the Weifang City waterproof material Co., long the source. Waterproof coating | long source | color polyurethane waterproof coating Weifang City for the source of waterproof material Ltd.
