Waterborne polyurethane waterproof coating is a single component liquid reaction curable polymer elastic waterproof coating material. The product does not contain solvents, cold construction, non-toxic, tasteless, with good adhesion and impermeability of cement and concrete surface, stone, metal products have a strong adhesion, chemical nature of the product stable, withstand long-term exposure to sunlight, high-strength, elongation, flexibility, good waterproof effect, after curing the coating can form a dense grass surface, solid, flexible waterproof coating, high tensile strength, elongation excellent on the base surface deformation adaptability, good low temperature performance, and waterborne polyurethane waterproof coating construction is extremely simple, no pollution, high performance, versatile, multi-functional advantages. The product has excellent flexibility, outstanding outdoor durability and UV resistance, suitable for roofing and waterproofing works directly exposed. Production technology leading domestic level, is a solvent-based polyurethane replacement. I. Features: 1-component packaging, cold construction, safe and simple, short construction period. Construction, to add water, is a polymer curing products. 2 can be wet (no clear water) or dry base surface construction, and grass-roots strong bond coating on the grass surface and wide adaptability. 3 For concrete, brick, mortar, metal, wood, glass, ceramics, plastics, insulation layer has a very strong adhesion. 4 green, solvent-free, non-toxic, tasteless, environmental pollution. Can be used for drinking water projects and food contact works. 5 film high tensile strength, elongation big, waterproof layer good integrity, ability to adapt to the grass-roots crack and deformation. 6 superior adhesion, high solids, water-based polyurethane waterproof small proportion of material per unit area with less cost-effective. 7 excellent cold and heat resistance, chemical corrosion resistance, aging resistance and mildew performance is superb. 8 outstanding outdoor durability and UV resistance, suitable for steel roofing and waterproofing works directly exposed. Second, the implementation of standards: JC / T846-2000 "building waterproof coating polymer emulsion" Third, the scope: 1. Widely used old roofing, steel tile, basements, tunnels, bridges, culverts, air defense and other engineering works waterproof can also be used to bond corrosion and wood flooring, cement board, asbestos, glass and steel products, ceramic products, tiles and other metal pipes, shop floors, pools, etc., can also be used for caulking sealant building structure. 2 plane, elevation, internal and external wall and planted roof and exposed directly to water projects. 3 bathrooms, kitchen, bathroom, balcony, windowsill seam, inside and outside the walls of the waterproof seal. 4. all kinds of industrial and civil type Color seams, high-strength light-load and large-span canopy waterproof. 5 various types of water tanks, underground fire water, sewage treatment pond and poor ventilation waterproofing works. 6 buildings crack repair, expansion joints, dividing joint cavity parts of the waterproof seal. The use of methods: 1 Basic requirements smooth dense, no oil, free from sand, no clear water. 2 For the grassroots have cracks and other defects should be repaired processing, yin and yang angle, deformation joints and other parts to be done to strengthen the layer processing. 3 need to be rust metal surface, polished, pre-coated layer of corrosion, rust treatment agent. 4 with a rubber scraper or brush the paint evenly coated with water-based polyurethane waterproofing material scraping the base surface, the coating thickness to meet the design requirements and should not be tainted brush, from the dark, layered and so on. 5 coat to dry at room temperature for about 12 hours under the time, each coated with sticky subject intervals, usually brushing 2-3 Road, Recommended dosage: 2kg / m, a thickness of about 1.2mm or so. V. Notes: 1 anti-sealed product should be stored in dry and ventilated place, storage temperature should be 5 or more. 2 coating construction should prevent rain water will, not dry before walking on solid non-waterproof layer. 3 to prevent damage to the waterproof layer sharp objects, decorative parts of the non-leakage waterproof layer should be done waterborne polyurethane waterproof coating protective layer construction.
