Дважды полиуретановый водонепроницаемое покрытие

<Description> 1)Polycondensation received isocyanate terminated pre-polymer double component waterproofing coating belongs to solidify waterproof materials, and the Group A is isocyanate terminated pre-polymer polycondensated by polyether and isocyanate, Group B is colored liquid composed of plasticizer, curing agent, thickening agents, coagulant agent and filler, Mix Group A and B evenly as rate and brush on the waterproofing substrate surface, form a elastisic and rubber-like coating film through cross-linking and solididying at normal temperature , which plays a role of waterproofing 2)Double component waterproofing coating forms seamless, integrate elasticity waterproof layer after solidifying , and improve waterproof and seeping resistance of the project, which is waterproof membrane that can not be attained. Especially the coating film has high elasticity and elongation , high adaptability to substrate craking or expansion. 3)Firm bonding with substrate , coating film has extreme bonding power with concrete,timber, metal, pottery and asbestos shingle,also can be used as bond. 4)Convenient application ,polyurethane coating film is a cold application waterproof coating ,just mix group A and B as rate when application and brush it on the waterproof substrate . 5)Easy maintenance ,only maintain the broken parts ,which can reach the oringinal effects of waterproofing ,save time ,save power and low cost . 6)Environmental product,and reduce the damage to the person and environment.. <Characteristic> ◊high elasticity and etensibility of film forming,no seamless ◊weather resistance,acid alkali resistance and strong adhesive properties ◊high performane of waterproofing and ageing resistance ◊environmental protecting product <Attentions>1)Two units, mixed in construction locate.2)Could be colorful.3)After curing, the membrane has high strength and elongation , it has good adaptability to fit for the foundation crack and the extention. The sevice life of the product is 25 years.The product is suitable for roofing, basement, toilet, swimming pool, etc.4)Basement treatment:Waterproofing base shall be strong, smooth and clean without particles on the surface. No peeling or cracking shall exist at the surface. The corners of the base shall be made into arcs with a radius of no less than 20mm or triangular. The drain slope, division seam, and air vent shall be carried out and treated according to design requirements. <Installation> Make primer: Mix DPU and solvent by A:B:Solvent=1:2:1, then brush primer on the foundation until it is Mix A:B=1:2. Scrach the coating by 3 times. The first layer curing needs 20-24 hours. When the first layer is solidifying, do the second layer. The direction of the second layer should be at right angles to the first layer. Then repeat the third one. If add protective layer, before the third layer is cured, scatter clean sand on its surface. After the membrane is cure, can begin the protective layer construction.<Specification>NOITEMINDEXIII1Sold content /%≥92%2Dry time of outside /h≤8hDry time of inside /h≤24h3Tensile strength Mpa≥1.92.454Fractrre elongation %≥4504505Water impermeability 0.3Mpa,30minImpermeability6Bending at low lemperature °C≤-3.57Bonding strength of moisture Mpa≥0.5
