Since polyurethane waterproof coating product quality testing with these characteristics, so the quality of the detection range includes the following aspects: product performance and workability testing; the film is generally used to detect performance and special properties. Polyurethane waterproof coating product quality testing and factory inspection can be divided into two forms of inspection. Factory inspection of the project are: Appearance; solids content; drying time; no treatment tensile strength; elongation at break without treatment; low temperature flexibility; impermeability or impermeability. Waterproof cement-based powder coating is generally waterproof coating with hydraulic properties of the polyurethane waterproof coatings, cement is the main bonding material, wherein the film-forming, hydrophobic component in the role of a catalyst, etc., together with cement, common in the substrate surface to form a dense film structure, a closed surface cracks, pores component polyurethane waterproof coating, thereby clogging the passage of water; and hydrophobic properties of waterproof polyurethane coating itself has waterproof paint manufacturers, can greatly improve the surface of the new surface tension, reduce water wetting ability, thereby enhancing the water repellency of the treated surface. 951 polyurethane waterproof coating, long the source of (certified), 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.
