Coating classification: color polyurethane waterproof coating

Core tip: brief introduction: color polyurethane waterproof coating is a kind of two-component reaction curing synthetic polymer waterproof coating Component A is polyurethane prepolymer obtained by polycondensation of polyether and isocyanate, and component B is a color liquid composed of plasticizer, curing agent, thickener, accelerator and filler When in use, the two components a and B are mixed in a certain proportion After mixing evenly, they are brushed on the surface of the base layer to be constructed After several hours, they react and consolidate to form a waterproof coating with elasticity, toughness and durability Features: the features of color polyurethane waterproof coating are as follows: 1) Color polyurethane Paint knowledge how about Akzo Nobel Powder Coating Recommended introduction: powder coating is a kind of coating with different form from general coating, which is in powder form It is a new type of coating, because of its own advantages and more and more known by people Let's introduce Akzo Nobel Powder coating Akzo Nobel Powder coating is a cost-effective coating solution, which can be applied to different kinds of products After the treatment of static electricity and fire baking, a tough and durable coating surface will be formed, with the least impact on the environment Since the introduction of this technology, powder coating has been able to continue to maintain the Introduction: color polyurethane waterproof coating is a kind of two-component reaction curing synthetic polymer waterproof coating Component A is polyurethane prepolymer obtained by polycondensation of polyether and isocyanate, and component B is a color liquid composed of plasticizer, curing agent, thickener, coagulant and filler When in use, the two components a and B are mixed in a certain proportion After mixing evenly, they are brushed on the surface of the base layer to be constructed After several hours, they react and consolidate to form a waterproof coating with elasticity, toughness and durability Features: the features of the color polyurethane waterproof coating are as follows: 1) the color polyurethane waterproof coating can be directly applied on the wet base surface, and can be applied 1-3 mm thick at a time; 2) the color polyurethane waterproof coating has large elongation, high strength and good elasticity; 3) the color polyurethane waterproof coating is dense, bubble free and pinhole free; 4) The color polyurethane waterproof coating has no tar component and benzene component, and has no pollution to the environment; 5) the color polyurethane waterproof coating has cold construction, which is convenient for construction; 6) the color polyurethane waterproof coating has chemical components such as corrosion resistance, acid resistance, alkali resistance and salt resistance; 7) the color polyurethane waterproof coating has strong adhesion with the base surface, and has strong water permeability Performance index: see the following table for performance index of color polyurethane waterproof coating: project performance index tensile strength / MPA 2.45 elongation at break /% 450 tear strength / (n / mm) 12 low temperature bending / ℃ - 35 impermeability (0.3 MPa, 30 min) impermeable solid content /% ≥ 92 drying time / h surface drying ≤ 8 solid drying ≤ 24 heating expansion rate - 4.0 ~ 1.0 Adhesive strength of wet base surface a / MPA 0.50 aging heating aging no crack and deformation artificial climate aging B no crack and deformation heat treatment tensile strength retention rate /% 80-150 elongation at break /% ≥ 400 low temperature bending /% ≤ - 30 alkali treatment tensile strength retention rate /% 60-150 elongation at break /% ≥ 400 low temperature bending /% ≤ - 30 acid treatment tensile strength retention rate /% 80-150 elongation at break /% ≥ 400 bending at low temperature /% ≤ - 30 tensile strength retention rate of artificial climate aging /% 80-150 elongation at break /% ≥ 400 bending at low temperature /% ≤ - 30 note: A only required for wet base surface of underground engineering; B only used for products with leakage Construction: the base course shall be flat, firm and fully dry (the underground works shall be free of obvious wet spots); the internal and external corners shall be made into arc shape, with the diameter of the internal corner greater than 50 mm and the diameter of the external corner greater than 10 mm Ø the reference dosage of 1 mm thick film is about 1.5-1.7 kg / m2 (generally 2.4 kg / m2 for 1.5mm thick film) ØØØØØØØØ、ØØØØØØØØØØØØØØØØØ和和和和和和 Before the coating is dry, it is strictly prohibited to walk on the waterproof layer and pay attention to protect it from damage; 5) pay attention to fire prevention at the construction site Packaging, transportation and storage: during the storage and transportation, it is required to strictly prevent the sun and rain, prohibit access to the fire source, prevent collision, and keep the packaging intact; the general shelf life is 12 months, and it can only be used after the shelf life is exceeded and it is rechecked to be qualified Home of coatings is specialized in coatings, diatom mud, paint coating, coating technology, fire retardant coating news and coating, diatom mud, paint coating, coating technology, fire retardant coating decoration knowledge and decoration renderings,
