Currently, professional institutes to carry out the construction of waterproof materials and construction waterproofing technology exchange activities, associations, a total of nine Information Network, a professional journal, magazine, newsletter two-component polyurethane waterproof coating, waterproof construction and journals regularly publish scientific articles count 10 species. These cross-industry social organizations and publications are following a lot of different forms carried out in order to promote the new materials, new technology development, and explore common problem eliminate leakage and improve the water quality of the project for the science and technology exchange activities subject. Made many insightful technical measures India policy recommendations. Such as the release of provisions in roof leaks and improve water quality of the project for the Ministry of Construction twice. As well as for the development, to amend the relevant waterproof technology standards, norms, have played a technical advisory role. However, it is worth noting that the current environment and conditions of work building waterproofing technology, there are still many problems. Mainly in the following aspects. 911 polyurethane waterproof coating made of two components. Component B is an isocyanate group-containing (-NCO) of the urethane prepolymer composition; A component is (-OH) containing polyhydroxy-based cured body filler, and a plasticizer, a thickener, an antifungal agent , thinners and other auxiliary components. A, B groups were mixed stir-component polyurethane waterproof coating prices, isocyanate to produce a chemical reaction with the hydroxyl colored polyurethane waterproof coating for sale, a holistic, flexible rubber film after full response, waterproof effect is remarkable, stick strong knot and tensile properties. Color polyurethane waterproof coating _ long a source of waterproof material (certified) _ waterproof coating provides long source from Weifang City waterproof material Limited.
