One-component polyurethane waterproof coating

I. Introduction of single-component polyurethane waterproof coating (also list ingredients tide cured polyurethane waterproofing coating) is isocyanate, polyether polyols as the basic ingredients, with various additives and fillers made by addition polymerization. By chemical reaction of polyurethane prepolymer -NCO end groups in contact with moisture in the air carried out at the grassroots level surface tough, soft and seamless rubber waterproof film. Second, product characteristics 1. Single-component, two-component polyurethane avoided because the ratio of the two components caused by improper proportion of inconsistent quality problems. 2. Relative bicomponent, its most important feature is the moisture can be used in heavy environments. 3. Cold construction, coating the whole seamless, strong adhesion, elongation, can adapt to the grassroots micro-cracking. 4. chemical corrosion resistance, aging resistance, mildew, water resistance, good watertight performance. 5. The relative two-component polyurethane, which is operable for a long time, after opening can run to in a long time. 6. Environmental protection, non-toxic pollution. Third, the scope 1. waterproofing works: for underground (building basements, underground garages, underground and open-cut method of channels, etc.), toilet and bath and pool, balcony, parking, interior and exterior, roofing, etc. 2. corrosion engineering: downspouts, metal, cesspools and other rust and corrosion. Fourth, technical indicators product performance standards: GB / T19250-2003 "polyurethane waterproof coating" one-component polyurethane waterproof coating Standard Test Item Standard Value I II 01 solid content,% ≥80 02 dry time, h ≤12 03 Drying time , h ≤24 04 impermeability, 0.3Mpa, 30min impervious 05 Tensile strength, Mpa ≥1.9 ≥2.45 06 Elongation at Break,% ≥550 ≥450 07 degree bend low, ℃ ≤-40 waterproof material Ten brand; paint brands; waterproof coating; waterproof material; waterproofing membrane; waterproofing works; waterproof investment; waterproof coating price; polyurethane waterproof coating; JS waterproof coating; waterproofing agent to join the bathroom waterproof material; Waterproof Building Materials; roofing materials; new waterproof materials; roofing materials; waterproof price; waterproof manufacturer; Fifth, use 1-based surface treatment: construction of the base surface must be dry, firm, smooth, no dust, no oil, water content <8℅. 2. base primer: Use the grassroots base surface treatment agent primer treatment, moisture barrier. 3. Node strengthening treatment: primer dry for node location, such as gutters, downspouts, Deformation, parapet, Yang angle peers spot coating 0.8mm thick reinforcement layer, spread to parts of the surrounding nodes 10cm range, within carcass reinforcement embedded fiberglass cloth. 4. waterproof layer brushing: Construction coating is usually carried out more than two passes. A rubber scraper or brush coating uniformly stir after brushing the base surface, brushing in two directions perpendicular to them several times to ensure that the coating penetration and bonding the base surface, the first layer After curing the coating can be carried out after construction left the second time. 5. Protective layer construction: waterproof layer has not been completed when dry, sprinkle sand in the base surface, increasing the adhesion surface protective layer. After the waterproof layer to dry, with 1: 2 cement mortar waterproof protective layer. 6, the reference amount: the thickness of 1.0mm, about 1.2 ~ 1.5kg / m2; thickness of 1.5mm, about 1.8 ~ 2.0kg / m2; thickness of 2.0mm, about 2.5 ~ 2.7kg / m2. Six Cautions 1. Paint open, the proposed one-time run out, failed to run out, and to be completely sealed, inverted saved. 2. Construction of the temperature 5 degrees Celsius or more appropriate, to ensure air circulation during construction. 3. material, add water that day, turpentine diluent water may cause quality problems. Seven, packaging and storage 20L / barrel, metal pail, cool place, away from the fire, the shelf life of six months.
