Product Description

Redispersible Polymer powder/RDP
RDP/ 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...

The RDP/Redispersible Polymer Powder is made by high temperature, high pressure, spray drying and polymerization with a variety of active enhanced micro powder, which can significantly improve the bonding ability and tensile strength of the mortar, good anti-fall, water retention and thickening construction performance, water resistance, freeze-thaw resistance, heat aging performance is outstanding, simple ingredients and easy to use. The new earth rubber powder has excellent fusion with cement, can be completely dissolved in the cement based dry mix mortar paste, after curing does not reduce the strength of cement, not only maintain the bonding effect, film formation and flexibility, but also has good weather resistance, stability, bonding performance and crack resistance, after drying, can effectively prevent the erosion of acidic air on the wall, not easy to powder after wet, deliquination. It can improve the performance of mortar, improve the strength of mortar, improve the bonding strength of mortar and various substrates, improve the flexibility and variable row of mortar, compressive strength, flexural strength, wear resistance, toughness, adhesion and water retention ability, and constructability. In addition, the emulsion powder with hydrophobicity can make the mortar have good water resistance.

RDP/Redispersible Polymer Powder is a commonly used organic cementation material, which is obtained by spray drying polymer emulsion such as polyvinylalcohol to protect colloids, and this powder can be re-evenly dispersed in water after water to form emulsion. The addition of redispersible emulsion powder can improve the water retention performance of the newly mixed cement mortar, as well as the bonding property, flexibility, impermeability and corrosion resistance of the hardened cement mortar.
At present, the main applications of dispersible emulsion powder in the market are: Vinylacetate and ethylene copolymer (VAC/E), vinylvinyl chloride and vinyllaurate ternary copolymer (E/VC/VL), vinylcacetate and ethylene and higher fatty acid vinylester ternary copolymer (VAC/E/Veo Va), vinylacetate homopolymer (PV) AC), styrene and butadiene copolymerization rubber powder (SBR), other binary and ternary copolymerization rubber powder, other formula rubber powder with functional additives, other formula rubber powder with functional additives and more than one kind of rubber powder, etc.

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. Application range

Characteristic
- Supply high flexibility 
- Improves workability 
- Improve water proofing of mortar
- Reduce water absorption
 - Better deformability
 - Increased adhesion to a variety substrates
 - Improved wetting of the substrate
 - Higher flexural strength and flexibility
 - Increased impact and abrasion resistance
 - Higher durability and freeze thaw resistance
Redispersible Polymer Powder RDP has no effect on rheological preperties and is a low-emissions,General-purpose powder in the medium Tg range.It is eminently suitable for formulating compounds of high ultimate strength.

Application:
1. Dry powder putty: improve the bonding strength, adhesion to the base layer, continuous film formation, dry powder putty is not affected by weather and humidity, making the product more stable, strong alkali resistance, and excellent waterproof performance.
2. Tile adhesive: It has extremely strong adhesion to the wall and bonding strength, which is necessary for high-grade tiles.
3. Tile refurbishment interface agent: good bonding strength, strong adhesion to the base surface of tiles and other surfaces that are smooth and non-absorbent.
4. External wall insulation: bonding mortar, plastering mortar and other construction mortars, especially suitable for flexible construction mortars.
