Dispersible polymer powder(RDP powder, VAE powder) is a white powdery polymer commonly used to modify cement-based or gypsum-based mortars.
Vinyl acetate-ethylene re-dispersible powder can be quickly redispersed into an emulsion after meeting water and has the same properties as the initial emulsion; that is, as the water evaporates during the coagulation and hardening of the cement mortar, the polymer particles are in the cement mortar. A film is formed, which acts like a polymer emulsion to modify the cement mortar. This film has high flexibility, weather resistance, abrasion resistance, and good adhesion to various substrates.
