The film makes up for lack of cement-based materials as well as a flexible polymer emulsion coating reswelling waterproof coatings, waterproofing defects and poor polymer cement-based waterproof coating specifications to improve the tensile strength of the polymer coating. Existing organic coating and high toughness high elasticity can be two-component polyurethane waterproof coating, there are inorganic materials and good durability, to the complementary advantages of both performance, play 'complex superposition' effect. It also has a high bond strength, non-toxic, tasteless, no air pollution. This paper describes the advantages of polymer cement waterproof coating, the analysis of various factors affecting the performance of polymer cement-based waterproof coating in order to pay attention to relevant personnel at the construction site and testing process. Polymer cement-based waterproof coating Features 1. water as the dispersion medium, non-flammable, non-toxic, harmless and no pollution. 2. High film strength, water resistance and durability. 3. In the wet base surface construction, and the substrate has good adhesion. The film has a certain breathability, waterproof layer from the drum phenomenon does not occur. 5. The construction convenient, fast drying and curing, a short duration. Two-component polyurethane waterproof coating, long the source of (certified), Shaanxi 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.
