PMC elastic polymer cement waterproof coating

PMC elastic polymer cement waterproof coating PMC elastic polymer cement waterproof coating (HC-211) is a highly durable polymer modified for special cement, supplemented by a variety of additives, prepared by the use of specific technology. This material is both high cement inorganic material strength, durability, good benefits, and good rubber-like elasticity and waterproof material, can be formed after coating high-strength, tough, durable, waterproof coating, and according to project needs formulated into various colors. Index requirements by the State Building Materials Test Center, the provincial and municipal quality inspection station testing, the product to meet the standards, technical performance has reached the international first-class level of similar products, successfully applied in many key, large-scale projects, has been unanimously praised the majority of users . Second, the technical characteristics 1, overall good, coherent whole waterproof layer, no seams, reducing the risk of leakage, improve the waterproof effect (1.5mm thickness of the cured coating impermeable at 30m high head pressure); 2 excellent elasticity and flexibility, according to project needs, elongation in the range of 80-2000% adjustable to withstand building settlement, shrinkage, high temperature deformation without cracking ability; 3. breathable waterproof, Construction Structure steam slowly through the waterproof layer naturally volatile and less prone to conventional waterproof material (such as web) hollowing phenomenon; 4, with the substrate adhesion strong, and its adhesive strength is about ordinary cement mortar 3-10 times; 5, cold-construction can be directly painted on the wet surface of the base without having to bake the base surface, do not delay the construction period, the construction operation is simple and flexible; 6, freeze-thaw resistance, high temperature resistance, corrosion resistance, UV radiation, weather resistance, excellent resistance to aging, can be used at exposed roofing; 7, non-toxic, non-polluting, non-volatile organic solvents, construction safety, harmless, is a green environmentally friendly products; 8, when the man appeared When leakage factors, can directly find the leak, local repair can be, and the web (easy hollowing) patch compared to saving time, effort, the provincial capital. , The construction can be mechanically pumped, can also be manually operated, no vibration, wiping pressure, convenient, low labor intensity; fast setting and hardening, high early strength and ultimate strength, hardened ground bright and clean, no shrinkage cracking, wear water outburst. After applying the product to the water by a certain percentage stir, pour smooth flat surface can be formed on the ground floor. Third, advanced technology compared to similar products currently marketed JS, a new generation of PMC-elastic polymer cement waterproof coating all aspects of performance, particularly water resistance, weather resistance has been greatly improved. It has the following Features: 1, a polymer with less polymer - cement ratio is low, elasticity (elongation ≥200%), high modification efficiency; (Note: polymer cement waterproof coating is usually a two-component liquid material an aqueous polymer dispersion powder mainly composed of cement, fillers, additives, two components reconciling the construction site currently marketed JS polymer cement waterproof coating material use ratio of liquid: powder = 10: 7, The PMC is liquid material: powder = 10:15, which means that the amount of powder PMC use more cement quantity, polymer-cement ratio that is lower, and elasticity is higher than the former); 2, and currently marketed JS compared to similar products, PMC greatly reduced water absorption (JS film 24h average water absorption 9.03%, while the PMC is only 1.95%; JS paint 7d water absorption 11.19%, while the PMC is only 4.47%), PMC high water , soaked in water without swelling after soaking the tensile strength, elongation at break retention rate; 3, PMC is a cement-based and other inorganic (inorganic 80% of the total system, only 20% organic matter), so a large number of cement-based materials can be effectively shield ultraviolet radiation and moisture intrusion; plus PMC using a highly durable polymer (a 20-year application example), did not use the water resistance, anti-aging, non-crosslinked poor polymer, so it has better UV resistance, weather resistance, excellent anti-aging properties. In summary, comprehensive technical performance PMC's leading domestic level, an ordinary JS replacements. Fourth, the performance index Item I of Type II Tensile strength: ≥1.5 Mpa ≥1.8Mpa Elongation at break: ≥200% ≥80% high temperature: 80 ℃, 5h no change in appearance temperature flexibility: Φ10mm stick -10 ℃, 2h No crack bond strength: Mpa ≥1.0 impermeability: 0.3MPa, 30min impervious water resistance: 7 days immersion, ≥90% strength retention aging resistance: 500 hours aging, strength, elongation retention rate ≥90% five , range 1, for a variety of water projects, such as roofing, interior and exterior, basement, toilet and bathroom, kitchen, tunnels, subways, pool, dams, roads, bridges and other water projects; curve, shaped structure, node, complex parts of the water treatment; 2, used as interface treatment agent to improve the bonding strength 3-10 times higher than ordinary cement mortar for bonding marble, tile and other veneer decoration materials, cement pipe joints and other binders; 3, for repair works, such as a variety of cement products, concrete pipes repair, masonry, old buildings repair defects or cracks, especially dynamic loads, vibration (such as roads, bridges, etc.) repair; 4, waterproof layer can be made of various colors, set of waterproof, decoration, insulation (with insulation material in combination) functions in one; 5, concrete protection, such as anti-carbonation, anti-salt corrosion; 6, the goods by liquid material: powder = 1: 2-3 tune into putty can be used for pointing or seal engineering. Sixth, the construction method: 1, the selection and application of the product types of construction sites in order to achieve a reasonable technical and economic results, according to different parts of the project, the choice of different types of products, roofing, wall and Deformation other parts, large deformation, should use high elastic PMC-I products (liquid material: powder: water = 10: 15: 1); and the project site in the basement, toilet and bath, and tunnels, the amount of deformation is small, should use low elasticity PMC-II type products. (Liquid material: powder: water = 10: 25: 2), the construction should not below 0 ℃ or the rain. This product is a two-component. When used, to join the liquid material, stirring slowly adding powder, stir until the compound free of aggregates and mixing time normally takes about 5 minutes, the slurry was filtered (filtered not stir open gob), then Apply 3-4 times to a total thickness of 1.5-2mm, can be waterproof after curing.
