Redispersible Polymer Powder (RDP)  is spray dried redispersible polymer powder,also named as Redispersible emulsion Powder or latex powder, designed for the construction industry to enhance the properties of dry mortar blends, able to Redispersible in water and  react with hydrate product of cement / gypsum and stuffing, form composite membrane with good mechanics intensity.

Mechanism of re-dispersible emulsion powder in mortar

1.After dispersed , re-dispersible emulsion powder filmand improve the mortar performance as the second adhesive bonding

2.Protective colloid were absorbed by mortar system (film polymer resin won’t disperse again and can not be damage by water )

3.Film polymer resin as reinforced materials distribute throughout the mortar system and increase the mortar of cohesion

Redispersible polymer powder 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 by coalescence 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.
