Product Description
Redispersible Latex Powder RDP
Redispersible latex powder (RDP) is a water-soluble redispersible powder. This RDP powder can be quickly dispersed into an emulsion after contact with water. It is an ethylene vinyl acetate copolymer with special polyvinyl alcohol as a protective colloid EVA) rubber powder. It is composed of dispersible colloids such as polymer resin, additives (inside and outside), protective colloids, anti-caking agent and other raw materials, and then produced by spray drying process of redispersible (EVA) powder.
The RDP Powder is mainly used in construction, has outstanding bonding strength, improves the flexibility of the mortar and has a long opening time, gives the mortar excellent alkali resistance, improves the adhesion of the mortar, flexural strength, waterproofness, plasticity, In addition to abrasion resistance and workability, it is more flexible in flexible mortar.
