RDP is composed of a special polymers made of powder adhesive after spray drying. This powder is contact with water can be dispersed again in soon after forming emulsion, and with the nature of the same as the initial emulsion, namely the film can be formed after the moisture evaporation, the film has high flexibility, high resistance to weathering and on various substrate with high caking property. the powder environmental protection, energy saving, high quality, used for powder materials, dry-mix mortar is an indispensable functional additives. 

Redispersible polymer Powder was further modified by the method of spray drying adding other substances to polymer latex. As a kind of polymeric powder with redispersible, It can be made into aqueous emulsion dispersed in the water. 

Characteristics

It can be emulsified with water and improve cohesion between mortar and its general supports;High impact resistance;It can also improve the constructability and mechanical properties of the mortar.

 Redispersible Polymer Powder is produced by spray-drying special water-based emulsion, mostly based on vinyl acetate and ethylene. It dissolves in water easily and quickly forms emulsion. Main content:

Protective colloid: Polyvinyl alcohol
