Product Description
Redispersible Polymer powder/RDPRDP/ Redispersible Polymer powder 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.
Redispersible Polymer powder/RDP(Vae)is mainly used in all kinds of dry-mix mortar, such as wall putty powder, ceramic tile adhesive, ceramic tile jointing agent, dry powder interface agent, exterior insulation mortar, self-leveling mortar, mending mortar, decorative mortar, waterproof mortar, etc...Technical data | Technical Date | HEARST RD 503M | HEARST RD 760F | HEARST RD 740H | HEARST RD 745W |

Redispersible VAE powder HEARST-503M is a product made of vinyl acetate-ethylene (VAE) copolymer emulsion as the main component, via spay drying process into flowable white polymer powder, which can be widely used for dry mixed mortar or powder construction material products.
Produced by spray-drying special water-based emulsion. Mostly based on vinyl acetate-ethylene. Dissolves in water easily and quickly forms emulsion. Its chemical properties are the same as original emulsion competely. Excellent flexibility in low temperature.
It can glue together different substrates, reinforce mortar struture and provide excellent adhesion at cement or gypsum based dry mixed mortar substate interface.
Redispersible Polymer Powder is widely used in construction areas especially used in construction mortar. Throughout the mortar system and increase mortar cohesion. Powder Material with Green Environment Protection. Welcome to contact me and get long time cooperation
Rdp/Redispersible emulsion powder can be physically mixed with other mechanical adhesives (such as cement, hydrated lime, gypsum, etc.) as well as various aggregates, fillers and other additives (such as cellulose, starch ether, lignocellulose, hydrophobic agents, etc.) to make dry mixed mortar. When the dry mortar is mixed in water, the latex powder particles are dispersed into the water under the action of hydrophilic protective colloid and mechanical shear. For example, in the dry shotcrete repair mortar, the dry mortar with the redispersible emulsion powder and water are mixed at the end of the nozzle for about 0.1s and then sprayed onto the construction surface, which is sufficient for the redispersible emulsion powder to fully disperse and form a film. In the early mixing stage, the emulsion powder has begun to affect the rheology and constructability of the mortar. Due to the different characteristics of the emulsion powder itself and the modification, this effect is also different, some help the flow effect, and some increase the thixotropy effect. The mechanism of its influence comes from many aspects, including the influence of the affinity of the emulsion powder to water when dispersed, the influence of the different education of the emulsion powder after dispersion, the influence of the protective colloid, the influence of the cement and water, the influence of the gas content of the mortar and the influence of the bubble distribution, and the influence of its own additives and the interaction with other additives. Among them, the more common view is that the redispersible emulsion powder usually increases the gas content of the mortar, thus playing a lubricating role in the construction of the mortar, and the emulsion powder, especially when the protective colloid is dispersed, the increase in the affinity for water and the teaching consistency helps to improve the cohesion of the construction mortar, thereby improving the workability of the mortar. Subsequently, wet mortar containing emulsion powder dispersion is constructed on the working surface. With the reduction of water at three levels, the absorption of the base, the consumption of cement hydration reaction, and the evaporation of surface water into the air, the resin particles gradually approach and the interface gradually fuse with each other, and finally become a continuous polymer film. This process mainly occurs in the pores of the mortar and the surface of the solid.Feature:Redispersible Polymer powder(Redispersible Latex powder) is the main raw material in production of internal, external wall putty, adhesive mortar and plaster mortar. the powder is specially applied as the agglutinant of basis materials on triple superphosphate, Talcum powder and white cement and so on. It can improve the adhesion properties water resistance, flexural strength and operability of the basis materials.
