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...

Redispersible Polymer Powder RDP is a thermoplastic material, it and inorganic cementing material constitute an ideal bonding system, each component brings its own properties and complement each other, together to form a cement and redispersible adhesive powder alone can not achieve the performance. The application of redispersible adhesive powder to mortar products can improve a variety of properties, such as: improve the bonding force; Improve cohesion; Reduce the elastic modulus; Increase flexural strength: increase flexure; Improve impact resistance; Improve wear resistance: reduce water absorption; Improve constructability: enhance durability; Improve water retention, etc.

The Redispersible Polymer Powder RDP can be quickly dispersed into an emulsion after contact with water, and has the same properties as the initial emulsion, that is, the water can be evaporated to form a film, which has high flexibility, high weather resistance and high adhesion to various substrates. In addition, the emulsion powder with hydrophobicity can make the mortar have good water resistance.
Redispersible emulsion powder is made of polymer emulsion by spray drying, mixed with water in the mortar, emulsified and dispersed in water, re-forming a stable polymerization emulsion, redispersible emulsion powder emulsified and dispersed in water, water evaporation, forming polymer film in the mortar, improving the performance of mortar, different redispersible emulsion powder has different effects on dry mortar.

RDP/Redispersible Polymer Powder is a thermoplastic resin powder prepared by spray drying polymer emulsion to remove water, and can be reduced to emulsion state after adding water. Due to this characteristic, it has been widely used in the fields where inorganic cementing materials need to be modified, such as single-component JS waterproof coating, polystyrene board bonding mortar for building insulation, flexible surface protection mortar, polystyrene particle insulation coating, ceramic tile bonding agent, self-leveling mortar, dry mix mortar, putty, etc. Redispersible emulsion powder can enhance the strength of the product, adding redispersible emulsion powder to the putty powder and mortar can increase its strength, and the improvement of hardness is very helpful. It has outstanding waterproof performance, good bond strength, can also increase the elasticity of mortar and have a long opening time, and give mortar excellent alkali resistance, can improve the mortar adhesion/adhesion, bending strength, wear resistance and constructability, in the flexible crack mortar has a stronger flexibility.

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.
