I. Introduction waterborne polyurethane waterproof coating Shu Fu Bai Shi waterborne polyurethane waterproof coating is a single component of volatile-type synthetic polymer highly flexible waterproof material with an aqueous polyurethane rubber asphalt as the base material, adding to the compound from other agents. It not only has high flexibility, high flexible polyurethane by weathering resistance, water resistance and stability of an aqueous rubber, and it is water-based, non-volatile solvent, nontoxic to humans. Second, product characteristics 1. Waterborne polyurethane waterproof coating Shu Fu Bai Shi waterborne polyurethane waterproof coating durability: in the complex base construction, form a seamless whole waterproof membrane, has excellent ductility, effective against grass crack, waterproof membrane to prevent breakage; with self-healing factor, can self-repair small scratches, stab wounds can automatically repair under the action of water. 2. Ease of use: one-component, no ingredients in the wet base surface construction directly, dry faster. 3. Economy: good aging resistance, has a longer life, saving maintenance costs, and can be compatible with a variety of materials, and can be complex to use, cost-effective. 4. Environmental protection: water-based materials, with water as a dispersion medium, non-toxic, tasteless, do not pollute the environment. Third, the scope 1. Old building roof, basement, bathroom, window sills and other water treatment. 2. Underground continuous bridges, culverts, civil air defense projects, pond, swimming pool. 3. Metal pipes, shop floors, pools of antiseptic use. 4. Expansion joints, dividing joint, the water port, wall tube seal. Fourth, technical indicators waterborne polyurethane waterproof coating Shu Fu Bai Shi waterborne polyurethane waterproof coating execution QB / T198-2013 "water-based polyurethane waterproof coating" standard. Solid content ≥50%; tensile strength ≥0.5MPa; elongation ≥450%; adhesion ≥0.5 MPa. Seven, packaging and storage of 25 kg / barrel; cool place, shelf life of 12 months.
