Polyurethane waterproof coating is an isocyanate, a polyether, etc. formed by addition polymerization of isocyanate group-containing prepolymer, with a catalyst, dry additives, anhydrous fillers, solvents, etc., is made by mixing machining processes The one-component polyurethane waterproof coating. Such as reaction curable coating (moisture-curing) coatings with high strength, elongation, good water resistance and other characteristics. Strong ability to adapt to the grassroots deformation. Polyurethane waterproof coating is a single-component liquid environmentally friendly construction waterproof coating, is no tar and asphalt additives imported polyurethane prepolymer as the basic ingredient. It is moisture in the air after contact with curing in the surface layer of solid grassroots tough anti seamless whole film. The first layer coating: After polyurethane A, B groups were and xylene by 1:l.5:0.2 ratio (weight ratio) fit into the mix asphalt polyurethane waterproof coating wash bucket, stirring with an electric mixer uniform (about 5min), with a rubber scraper blade coating a layer of paint or a paint brush polyurethane waterproof coating type, thickness should be uniform, scratch amount 0.8 ~ 1.0kg / m is appropriate, from the inside out back with the operation. The second layer of film: After the first layer of the coating, the coating cured when sticky polyurethane waterproof coating material ratio method according to the first pass, the second time the coating operation, for the uniform coating thickness, scraping Tu direction perpendicular to the direction must first pass Scratch, scratch the same amount and the first pass. Color polyurethane waterproof coating, polyurethane waterproof coating, long a source of waterproof material provided by the Weifang City for the source of waterproof material Limited. Weifang City for the source of waterproof material Ltd. (www.jiuyuanfangshui.com) strong, credible, Shandong Weifang waterproof, moisture-proof materials industry has accumulated a large number of loyal customers.
