Redispersible polymer powder(RDP) produced by spray-drying special water-based emulsion, mostly based on vinyl acetate-ethylene (VAE),
and then obtained a free flowing organic polymer powder. It can re-disperse in water, and form a film after water evaporation bycoalescence of individual polymer particles. The 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 substrate interface.
