Choose waterproof coating four principles should be considered: (1) the extent of ground deformation, structure, local annual temperature, daily temperature and vibration factors waterproof polyurethane coating sold, should be selected to adapt the tensile properties of waterproof coating. (2) According to the degree of exposure of roofing coating should be selected UV resistant, heat aging retention adapt waterproof coating. (3) According to the calendar of local maximum temperature, minimum temperature, roof slope and conditions of use and other factors, you should choose the heat resistance and low temperature flexibility to adapt to the waterproof coating. So as to prevent the flow or cold crisp. (4) Roof drainage slope is greater than 25%, should not be used too long dry film waterproof coating waterproof cement-based powder coating is generally waterproof coating with hydraulic properties of the polyurethane waterproof coatings, cement is the main bonding material, one of the film-forming, hydrophobic component in the role of a catalyst, etc., together with cement two-component polyurethane waterproof coating, the substrate surface together form the structure of dense polyurethane film waterproof paint manufacturers, closed surface cracks, pores, thus clogging water The channel; and hydrophobic properties itself has waterproof coating, can greatly increase the surface tension of the new surface, reduce water wetting ability to improve water repellency treatment of surfaces. Waterborne polyurethane waterproof coatings, polyurethane waterproof coating, Weifang City for a long time source is the source of waterproof material Limited. Weifang City for the source of waterproof material Ltd. (www.jiuyuanfangshui.com) strong, credible, Shandong Weifang waterproof, moisture-proof materials industry has accumulated a large number of loyal customers.
