911 Non-tar polyurethane waterproof coating

Product Description: HC-19 911 Non-tar polyurethane waterproof coating is a polyurethane polymer as the main body of the two-component chemical reaction type waterproof coating, it is by having an isocyanate group (-NCO) of the polyurethane prepolymer (Part A) and containing multiple hydroxyl (-OH) curing agent, carbon black, curing agents, preservatives, thickeners, catalysts and other additives made by mixing (Part B) components. A and B were mixed uniformly by a certain percentage, the overall water cured to form a flexible film. Advantages: 1, does not contain tar, pungent odor small, reducing pollution. 2, cold construction, easy operation, construction safety. 3, liquid construction, room temperature curing, curing time is short, strong bond, waterproof, high impermeability. 4, elongation, cold and heat, corrosion resistance, good anti-aging properties. Roofing 1, various roof waterproofing works, such as concrete, bamboo, wood, steel, tile structure: the scope of application. 2, the underground construction waterproofing works, such as the basement concrete floor, interior and exterior, retaining walls, tunnels, wells and pits. 3, waterproof construction of various buildings, such as the bathroom, kitchen, non-food, swimming pools, flower beds, sluice ground, inside of the walls, construction joints, expansion joints, wall pipe, the water vent. 4, adhesive anti-corrosion: bondable wood, cement, asbestos products; and for pipeline external corrosion, corrosion floor, corrosion pool. Main Specifications: Standard: GB / T19250-2003 Testing items Solid content (%) ≥92 Drying time (h) hard work table dry ≤8 ≤24 flexibility at low temperature (℃) ≤-35 no crack impermeability ( 0.3Mpa, 30min) impervious Tensile strength (Mpa) ≥1.90 elongation (%) ≥450 Construction steps: 1, the base surface treatment: construction of surface requires a solid, flat, dry and no clear water, no dust, no oil , breakage need to fill low-lying smooth. 2. Ingredients: According to Part A Materials: Material Part B = 1: 2 ratio by weight, the first material is poured into Part A and Part B is then added to the material in the container, and stir until the black color can use. 3. Construction: The construction material is usually carried out in two passes, will paint mixed with a rubber scraper or brown brush evenly on the base plane, scraping should be repeated several times in both directions perpendicular to ensure paint penetration and bonding base surface, when the first coat is dry curing the second layer can be painted. (If the overlay coating glass fiber cloth or non-woven fabric to better increase its water resistance). 4, the protective layer construction: In order to increase the adhesive force between the waterproof layer and the protective layer in front of the second floor has not been cured coating on its surface sprinkled Coarse or fine stone rice, make a protective layer and waterproof layer bond between the firm. 5, material consumption: 1mm thickness of about 1.2 ~ 1.4kg / m2,1.5mm about 1.7 ~ 2kg / m2,2mm about 2.5kg / m2 Notes: 1, such as viscosity of the material found in Part B is too large (especially in the winter construction ), not to facilitate the construction, can be added a small amount of toluene or xylene diluted amount can not exceed 10 percent of Part B material. 2, as do the film bubble generation (usually caused by higher base surface moisture content), should be a place bubbling cut exhaust moisture until dry and then paint repair. 3, the construction temperature should be above 5 ℃, the construction should maintain good ventilation; after coating formulation should be used within 20 minutes. 4, the product should be sealed and stored in a dry, avoid sunlight, rain place, storage period of six months. Packaging: Product packaging into 30kg / set, 25 kg / set, 4.5kg / set.
