(RDP) MANUFACTURERS REDISPERSIBLE POLYMER POWDER is a free-flowing, white powder obtained by spray drying of an aqueous vinyl acetate-ethylene copolymer dispersion. Redispersible polymer powders are polymer emulsions which have been converted by spray drying (atomizing the aqueous polymer dispersions in a stream of hot air) to free flowing powders. When blended with water, these powders redisperse back into liquid emulsions with essentially identical properties to the original emulsions.
Redispersible Polymer powder(ordinary type) 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. It can improve the performance of mortar, raise the strength of the mortar, improve the bonding strength of mortar with different base material, improve the mortar flexible and variable line, compressive strength, flexural strength, abrasion resistance and toughness, stick relay and water retention, constructability.
