Ethylene And Vinyl Acetate Copolymer VAE

1. Construction industry: as a water-retaining agent and retarder of cement mortar, mortar has pumping property. In plastering mortar, gypsum, putty powder or other building materials as adhesive, improve smearing and extend the operating time, but also reduce the amount of cement. HPMC water retention performance makes the slurry after daub will not dry too fast and crack, enhance the hardening strength. 2. Ceramic manufacturing: widely used as adhesives in the manufacture of ceramic products. 3. Coating industry: In the coating industry as a thickening agent, dispersant and stabilizer, in water or organic solvents have a good compatibility. As a paint stripper. 4 ink printing: in the ink industry as a thickening agent, dispersant and stabilizer, in water or organic solvent has a good compatibility. 5. Others: This product is also widely used in leather, plastic, paper products industry, fruit and vegetable preservation, textile industry and pharmaceutical industry.

PVA is an organic compound with the chemical formula [C2H4O] N. It has the appearance of a white flake, flocculent or powdered solid and is odorless. Soluble in water (above 95℃), slightly soluble in dimethyl sulfoxide, insoluble in gasoline, kerosene, vegetable oil, benzene, toluene, dichloroethane, carbon tetrachloride, acetone, ethyl acetate, methanol, ethylene glycol, etc. Polyvinyl alcohol is an important chemical raw material, used in the manufacture of polyvinyl acetal, gasoline resistant pipeline and vinylon, fabric treatment agent, emulsifier, paper coating, adhesives, glue,etc.

RDP is water-soluble redispersible powder, a copolymer of ethylene and vinyl acetate, with polyvinyl alcohol as protective colloid. By adding redispersible latex powder, the properties of cement or gypsum mortar can meet the needs of various construction buildings. Function: emulsion powder disperses into a film and plays an enhanced role as a second adhesive; Protective colloid is absorbed by mortar system (film will not be destroyed by water or "secondary dispersion"); The polymer resin is distributed in the whole mortar system as reinforcement material, which increases the cohesion of mortar.
