Polyurethane waterproof coating performance test methods and other types of building waterproof coating performance test method are similar waterproof polyurethane coating, but also has its own peculiarities. With the development of building waterproof materials industry, China's quality and performance testing of waterproof material also more and more attention, the state has issued GB / T16777-1997 "Test methods for building waterproof coatings" for the State Economic and Trade Commission issued a JC / T894-2001 "polymer cement waterproof coating" building materials industry standards. Chapter based on these national and industry standards, introduce detection methods waterproof coating. Waterproof cement-based powder coating is generally waterproof coating with hydraulic properties, as the main bonding material is cement, under which the role of catalyst deposition, the hydrophobic component, etc., together with cement waterproof polyurethane paint manufacturers, common the substrate surface to form a dense film structure of two-component polyurethane waterproof coating, closed surface cracks, pores, thus clogging the passage of water; and hydrophobic properties of waterproof coating itself has, can greatly increase the surface tension of the new surface, reducing water wettability, thereby improving the water repellency treatment of the surface. Polyurethane waterproof coating prices, long the source of (certified), Weicheng polyurethane waterproof coating provided by the Weifang City waterproof material Co., long the source. Weifang City for the source of waterproof material Ltd. (www.jiuyuanfangshui.com) Shandong Weifang, waterproof, moisture-proof material leader, over the years, the company is implementing the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customer needs. In the long waterproof material source leadership with the staff warmly welcome all inquiries negotiations to create a source of long waterproof material better future.
