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. The purpose primer coating polyurethane waterproof coating is two-component polyurethane moisture barrier grassroots waterproof coating, waterproof coating to prevent falling from the drum, strengthening the grassroots level, to improve the adhesive strength of the coating and base the price of polyurethane waterproof coating, the coating is not the people's livelihood peeling, pinholes appear to prevent the coating layer, porosity and other defects. Waterproof polyurethane coating formulated rubber bottom. Group A and Group B points polyurethane primer designed for use in sub-1: 3-4 (mass ratio), mixing evenly wholesale polyurethane waterproof coating can be applied to construction. Group A points can also be added to xylene and Part B mixing evenly Xiangfan polyurethane waterproof coating, mass ratio of 1: 1.5: 2. Polyurethane waterproof coating to construction. Complex parts of a small area, angle, pipe roots, floor drain and drain, etc., by brush, a large area of ??usable length of the hair roll roll. Coating thickness should be uniform, can not show the bottom of uneven thickness. Generally the amount of (0.15 ~ 0.2) kg / m2. Dried over four hours, before the next process of construction. Two-component polyurethane waterproof coating, long the source (online consultation), Xiangfan polyurethane waterproof coating provided by the Weifang City for the source of waterproof material Limited.
