防水材料

coating CE Certificated China well known trade mark "Yuhong" Brand It is a fluid applied polymeric waterproof coating which consists of two reaction components. (1) One component is polyurethane monomer made from polyether and isocyanate through fasculation. (2) The other component is colorful liquid made up of plasticizing agent, solidified agent, thickener, coagulant and bulking agent. Prior to application, the two components should be mixed at a certain percentage. (3) After fully mixed, the coat is applied by brushing on the substrate, which will solidify and become an elastic, tenacious, and lasting waterproof film in several hours reaction. ·Specification: The SPU-311 product is classified into type I and type according to its strength performance and applications. The product abides by the national standard G BT 1 9 2 5 02 0 03 for two-component polyurethane coating as specified in the following table. ·Physical Properties of two-component polyurethane waterproofing coatingNo. Itemι∏1 Tensile strengthMPa ≥ 1.9 2.45 2 Elongation at break ≥ 450 450 3 Fracture strength(Nmm) ≥ 12 14 4 Flexibility at low temperature0C ≤ -355 Water impermeability 0.3MPa 30min impermeable6 Solid content ≥ 92 7 Surface drying timeh ≤ 8 8 Hard drying time h ≤ 24 9 Hear extension and compression ≤ 1.0≥-4.010 Bond strength of wet substrateMPa 0.5011 Aging at maintained elongationaging when heating No cracks and deformationAging by artificial climate No cracks and deformation12 Heat treatmentTensile strength retention 80 150Elongation at break ≥ 400Flexibility at low temperature ≤ -3013 Alkali treatmentTensile strength retention 60 150Elongation at break ≥ 400Flexibility at low temperature ≤ -3014 Acid treatmentTensile strength retention 80 150Elongation at break ≥ 400Flexibility at low temperature ≤ -3015 Aging by artificial climateTensile strength retention 80 150Elongation at break ≥ 400Flexibility at low temperature ≤ -30a Requirement only for wet substrate of subterranean engineering b Only for products exposed outside. ·Features: (1) The product can be used in wet substrate and have strong bonding capacity. (2) The product has high strength, high elongation and good elasticity. (3) The coating layer can be applied as thick as required and the coating membrane can be compact without bubbles and pinholes. (4) The product does not contain any solvent such as benzene, coal tar, thus no pollution to the environment. (5) As a liquid product, it is convenient for construction and when construction, no heating is needed. (6) The film is formed through chemical reaction which is of waterproofing, corrosion-resistant, mildewproof and frost-resistant with high water impermeability. ·Application Range (1)The waterproof and dampproof industries such as basement, lavatories, bathroom, kitchen, pool, refrigeration storage, lawn, especially in the subterranean project whose substrate is hard to be desiccated. (2) waterproofing project of non-exposedroof.
