Polyurethane waterproof coating is a kind of prepolymer containing Isocyanate which is prepared by addition polymerization of Isocyanate, polyether and so on, with catalyst, anhydrous additive, anhydrous filling agent, solvent, etc., one-component polyurethane waterproof coating made by mixing and other processes. This kind of coating is reaction-curing (moisture-curing) coating with high strength, high elongation, good water resistance and so on. Strong adaptability to the deformation of the grass roots. Polyurethane waterproof coating is a kind of one-component environmental protection waterproof coating applied in liquid state. It is based on imported polyurethane prepolymer without tar and asphalt. It is the moisture in the air after contact curing, in the surface of the base to form a layer of strong and tough seamless integral anti-film.
(1) can be directly applied on a variety of wet or dry base surface.
(2) with strong adhesion to the base surface, film in the polymer material can penetrate into the base surface micro-cracks, strong follow-up.
(3) the film has good flexibility, good adaptability to base expansion or cracking, and high tensile strength.
(4) environmental protection, non-toxic tasteless, non-polluting environment, no harm to the person.
(5) good weather resistance, high temperature does not flow, low temperature does not crack, excellent anti-aging performance, oil resistance, wear resistance, resistance to ozone, acid and alkali erosion.
(6) the coating film is compact, the waterproof layer is complete, there is no crack, no Pinhole, no bubble, and the water vapor permeability Coefficient is small. (7) the construction is simple, the construction period is short, the maintenance is convenient (8) according to the need, may deploy each color (9) the quality is light, does not increase the building load。
