ZHUOJUN redispersible polymer powders are produced by spray-drying special water-based emulsion and are mostly based on vinyl acetate-ethylene. They dissolve in water easily and quickly forms emulsion. Their chemical properties are the same as original emulsion completely. They have excellent flexibility in low temperature. The RDP powders can glue together different substrates, reinforce mortar structure and provide excellent adhesion at cement or gypsum based dry mixed mortar substrate interface.
