Polymer modified bitumen coating refers to the asphalt-based material, modified bridge with waterproof coating, made of water emulsion or solvent-based waterproof coating with synthetic polymers. Such coatings in flexibility, crack resistance, tensile strength, high temperature performance and other aspects of life has greatly improved over the asphalt-based coatings. Variety of recycled rubber modified asphalt waterproof coating, water emulsion neoprene rubber asphalt waterproof coatings and SBS modified bitumen coatings. It is suitable for Ⅱ, grade Ⅲ, Ⅳ grade waterproof roof, floors, concrete basement waterproofing and toilet. Waterproof coating characteristics: (1) waterproof coating prior to curing and viscous liquid, therefore, the construction not only in the horizontal plane, but also in the facade, Yang angle and a variety of complex surfaces, to form a seamless waterproofing membrane integrity ; without heating (2) the use of waterproof coating, reducing environmental pollution, and easy operation of the color polyurethane waterproof coating, improve working conditions; waterproof layer (3) formed small weight, especially for light roof waterproof. (4) waterproof membrane forming a greater extensibility, water resistance and weather resistance, can adapt to small changes in the grassroots cracks. (5) The host material coated waterproof coating, is both waterproof layer, but also the water-based polyurethane adhesive waterproof coating, it is easy to bond quality assurance and maintenance is relatively simple. Especially the implementation of the base crack, construction joints, water bucket and runs through some of the sites likely to cause leakage around the tube, etc., can easily be enhanced brushing, patch and other operations. Polyurethane waterproof coating, long the source of (certified), Chongqing 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.
