RDP (Re-dispersible Polymer Powder) is a white powdery polymer made of emulsion by spray drying. In contact with water, the emulsion will disperse quickly and have the same film forming characteristics as the original emulsion. This film has high weather resistance, high toughness and high adhesion to different substrates.
Key ingredients include polymer (Vinyl acetate-ethylene copolymer - VAE), additives, protective colloid (polyvinyl alcohol), and anti-caking agents.
It dissolves in water easily and quickly forms emulsion. It features high adhesion, water resistance, processability, and heat insulation. Primarily used in cement mortar as an additive for the construction industry.
