One-component waterborne polyurethane waterproof coating

One-component waterborne polyurethane waterproof coating I. Introduction: HC-23 component polyurethane waterproof coating is a polyurethane terpolymer and by chemical modification, change and improve the performance of polyurethane waterproof coating, increasing the bonding strength, weather resistance, low temperature flexibility and impermeability. To overcome the traditional polyurethane environmental damage, poor weather, damp base surface not construction and other ills. Material is black, white, can be selected according to engineering design. Second, product characteristics: 1. have good water resistance, weather resistance. 2. The coating was closed overall performance long-term stability. 3. The high temperature 100 ℃ not sag, low temperature -40 ℃ not crack. 4. Green products, non-toxic and harmless. 5. The construction safety, simple process. 6. The wet construction base surface can effectively improve the progress of the project. Third, use: for buildings and construct water projects. Such as: roofing, Bathroom, roads, bridges, culverts, underground engineering and equipment, pipeline leakage outside waterproof. Fourth, use: 1. Construction using brush, roller and brush brush do. 2. When a thick coating of water can be added to facilitate the construction of 8% stir well before use, add water immediately after the run should not be stored. Fifth, the construction process: the pre-construction of the base surface clean, handle the slab and deformation joint, first brushing the base paint, painted a second time after the paint is dry, while a layer of matrix material (non-woven or glass fiber cloth), and finally brushing paint on top of the carcass at least three times. Each time material in 0.4-0.5kg / m. Shop carcass material to be compacted smooth, no bubbles, no wrinkles, take the side of 5-10cm (refer polymer waterproof coating construction process XT-301). Bathroom toilet, basement and other waterproof seamless construction such as flat-free shop matrix material, the root canal must be added to the carcass material shop. Acceptance by national technical specifications waterproofing standards for acceptance. VI, packaging Weight: 50 kg / barrel
