🔍 Product Description

RDP (Redispersible Polymer Powder) manufacturer, stable quality and competitive price.

Redispersible polymer powder (RDP) is produced by spray-drying special water-based emulsion, mostly based on vinyl-acetate-ethylene (VAE), obtaining a free-flowing organic polymer powder. It can re-disperse in water and form a film after water evaporation. This film acts as an organic binder to glue together different substrates, reinforce mortar structure, and provide excellent adhesion at cement or gypsum-based dry mixed mortar interfaces.
