Dare to use it as the DPS waterproof material (concrete protective agent) for the Three Gorges Dam, nuclear power plant and other high requirements of the United States. Impermeability level above 11! Many permanent condensates are not detected by DPS.
Do not fight price war. Ask for unlimited low price communication. Of course, the wireless low is selling water to you
U.S.A C O -MA-SEAL ® Permanent liquid DPS waterproof material - concrete protective agent
DPS， It is the abbreviation of Deep Penetration Sealer. In the definition of domestic national standards, it is water-based (or water agent, water-based) permeable crystalline inorganic waterproof material. The American CO-MA-SEAL permanent condensate DPS waterproof material was used in the United States in the 1920s, mainly for large areas of underground military bunkers, playing a role in waterproof and moisture-proof.
U.S.A C O -MA-SEAL ® Permanent condensate DPS waterproof material is Water based permeable crystalline waterproof material (The advantage of water-based is that when there is water in the concrete structure, it can continue to react until the water is "absorbed"). Its waterproof mechanism is to produce chemical reaction with free alkali and other active ingredients in the concrete, generate stable dendritic crystal colloid, effectively block the micro cracks and capillary voids in the concrete, so that the concrete structure has good waterproof function and better compactness and compressive strength. The permeability of high layer reaches about 30mm. At the same time, it can effectively prevent the erosion and damage of acid and alkali substances, oil stains, algae, salt, etc. to concrete.
It can be used for any concrete base surface. It can only be used for concrete base.
American CO-MA-SEAL permanent liquid DPS waterproof material is not only concrete waterproof material, but also concrete protective agent: it is acid resistant, alkali resistant, corrosion resistant, and can resist high temperature changes! It can also resist the damage and erosion of chloride ions on concrete.
Main performance description:
1、 American CO-MA-SEAL permanent condensate DPS waterproof material is permeable crystalline waterproof material, so leveling layer is not required. It can completely penetrate into the concrete structure, so no protective layer is required;
2、 It needs to be fully contacted with the concrete to achieve a good waterproof effect, so the laitance and dust on the surface of the concrete structure must be cleaned up first. Rapid solidification shall be used at the crack first cement Wait for repair;
3、 It is a waterproof material with small density of water agent, which can be sprayed twice on the concrete base directly without additional curing. Low construction cost and fast construction progress;
4、 The penetration degree of the high layer can reach about 30mm (general concrete). Impermeability grade reaches above S11;
5、 Good acid, alkali and corrosion resistance. It can resist the influence of temperature change on concrete. It can resist the penetration damage of chloride ion to concrete. It can enhance the compressive strength of concrete structure surface, etc;
6、 American CO-MA-SEAL permanent condensate DPS waterproof material is inorganic waterproof material, so it will not deteriorate. The effect is very stable. After construction, the waterproof efficiency is basically the same as the service life of the concrete structure;
7、 It can be constructed on the wet concrete working surface, but there should be no open water. It can be constructed on the back surface;
8、 Because it is a deep penetration crystalline waterproof material, there will be no traditional problems such as aging, untight lapping, delamination and sliding;
9、 It can play a good role in protecting concrete, reinforcement, etc;
10、 It is completely environmentally friendly and can be used as the interior wall of swimming pool, sewage pool, water plant, etc;
11、 Because it is a deep penetration crystalline type, it is not a surface sealed bead, but hydrophilic.
Special reminder: the waterproof material of American permanent liquid DPS is water agent, colorless and tasteless, so there are many counterfeits. It depends on whether there is an import declaration form, certificate of origin, etc. The permanent condensate DPS imported from the United States is * * * permanent condensate DPS. Compared with the domestic ones, the quality gap is too large and the price is absurdly low (material cost per square meter). There are many so-called English brands in the market that are counterfeit imports! Search abroad (Baidu can only search domestic) to determine whether there are relevant manufacturer websites, brands, construction cases and other materials abroad! You can also check the time when a so-called English brand registered its trademark in China at a glance! The so-called domestic production of American technology is more untrustworthy, because there is no relevant evidence!
