ZCT-640 one-component oil-based polyurethane waterproof coating is a one-component polyurethane waterproof coating made of isocyanate-based prepolymer formed by addition polymerization reaction of isocyanate, polyether, etc., with catalysts, anhydrous additives, anhydrous fillers, solvents, etc., and processed by mixing and other processes. This type of coating is a reaction-curing (moisture-curing) coating, which has the characteristics of high strength, large elongation and good water resistance. It has strong adaptability to grassroots deformation. Polyurethane waterproof coating is a one-component environmentally friendly waterproof coating with liquid construction, which is based on imported polyurethane prepolymer and has no additives such as tar and asphalt. It is the moisture in the air that solidifies upon contact, forming a strong and tough seamless monolithic film on the surface of the base layer.

Product features:
◆ The coating film is dense, no pinholes, no bubbles, and strong adhesion
◆ Superior environmental performance, no benzene solvent, no coal tar components
◆ Chemical reaction to form a film, resistant to water, corrosion and mildew
◆ The coating film has rubber characteristics, high elasticity, high strength, and high elongation
◆ Good water resistance, can be used for waterproof projects such as basements that have been in moisture or water immersion for a long time
◆ It can be applied to the waterproof construction of complex buildings, and has strong adhesion to the base layer (such as concrete, stone, wood, metal, etc.).

Product classification
