Isocyanate is one of the main raw material for polyurethane waterproof coating, commonly used are the following three: The first two-component polyurethane waterproof coating, polyphenyl polyisocyanate polymethine, namely crude xylene methane diisocyanate (crude MDI) also known as polymeric MDI, also known as PAPI. Second, toluene diisocyanate, that TDI. Greater use of polyurethane waterproof coating TDI, European countries tend to use pure 2951 polyurethane waterproof coating, 4-TDI or TDI-65, the United States and most of the use of TDI-80. Polyurethane waterproof coating is a diisocyanate, polyether formed by the addition polymerization of isocyanate group-containing prepolymer polyurethane waterproof coating prices, together with the catalyst, anhydrous additive, anhydrous fillers, solvents, etc., by mixing processing into single-component polyurethane coatings. Class coating reaction curing type (moisture-curing) coatings with high strength, elongation, good water resistance characteristics. Adaptable to the grassroots deformation. Polyurethane waterproof coating is a liquid one-component construction of environmentally friendly waterproof coating polyurethane waterproof coating, it is imported polyurethane prepolymer as the basic ingredients, no tar and asphalt additives. It is contact with moisture in the air after curing, the primary surface layer of solid tough seamless overall anti-film.
