Basic information
Redispersible Polymer Powder (RDP) is a free-flowing, odorless, non-toxic white powder that is a spray-dried powder of polymer emulsions made from special water-based emulsions. The redispersible Polymer powder is re-emulsified with water and has the same properties as the original emulsion, that is, the water evaporates to form a translucent, highly malleable and ductile film. The film has adhesive, wear-resistant, waterproof, dispersion, emulsification, film coating, gelling, colloidal protection and other properties to ensure long-term durability, low temperature flexibility.

Product feature
Good film formation. RDP forms a thin, high-tension, high-viscosity film on the substrate to prevent moisture.
Excellent water resistance. RDP effectively prevents water intrusion, and only a thin layer can form an effective waterproof barrier.
Strong adhesion. RDP polymer binder can significantly improve the adhesion and bond strength of mortar.
Flexibility to prevent cracking. RDP enables the mortar to adapt to changes in the external environment. Thus effectively prevent the mortar from cracking due to temperature change, improve the water retention and water resistance of the mortar.
Excellent processability. RDP makes the mortar easy to mix and smooth to apply, reducing labor costs and working time.
