Water-based polyurethane waterproof coating is a one-component polyurethane waterproof coating made of isocyanate, polyether and other prepolymer containing isocyanate group by addition polymerization reaction, with catalyst, anhydrous additives, anhydrous filler, solvent, etc., by mixing and other processes.
Water-based polyurethane waterproof coating for the reaction-curing type (moisture-curing) coating, with high strength, elongation, good water resistance and other characteristics. The ability to adapt to grass-roots deformation is strong. Polyurethane waterproof coating is a liquid construction of one-component environmentally friendly waterproof coating, is based on imported polyurethane prepolymer as the basic ingredients, no tar and asphalt and other additives. It is air moisture contact after curing, in the grass-roots surface to form a solid tough no-joint overall anti-film.
Water-based polyurethane waterproof coating product classification
(1) One-component polyurethane waterproof coating
Single-component polyurethane waterproof coating is a reactive flexible waterproof coating made of isocyanate, polyether as the main raw material, with a variety of additives. The product has good physical properties, strong adhesion, wet curing at room temperature. Some polyurethane waterproofing coating painted out of the film has a slightly sticky situation, in the case of performance standards, also belong to qualified.
A, performance, characteristics
1. products with high strength, high elongation, high solid content, strong adhesion.
2. Natural leveling, good extensibility, can overcome the leakage caused by the cracking of the grass-roots level.
3. Normal temperature construction, easy to operate, non-toxic and non-hazardous, excellent weathering and aging resistance.
4. convenient construction, overcoming the shortcomings of two-component polyurethane waterproof coating need to measure and mix, to ensure the stability of product quality and waterproofing effect of the project.
Water-based polyurethane waterproof coating scope of application
Suitable for roof and toilet, basement, cistern, wall waterproofing, anti-seepage, moisture-proof.
