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...

With the increase of the content of redispersible emulsion powder/Rdp, the whole system develops in the direction of plastic. In the case of high emulsion powder content, the polymer phase in the cured mortar gradually exceeds the phase of the inorganic hydration product, the mortar has a qualitative change, and becomes an elastomer, while the hydration product of the cement becomes a "filler". The dispersed film of dispersible emulsion powder distributed on the interface plays another key role, that is, it enhances the adhesion of the contact material, which is good for some difficult surfaces, such as very low water absorption or non-water absorption surfaces (such as smooth concrete and cement material surface, steel plate, homogeneous brick, vitrified brick surface, etc.) and organic material surfaces (such as EPS board, plastic, etc.). It is especially important. Because the bonding of the mechanical adhesive to the material is achieved through the principle of mechanical embeddings, that is, the hydraulic slurry penetrates into the gap of other materials, gradually solidifies, and finally the mortar is attached to the surface of the material like the key embedded in the lock. For the above difficult surface, due to the inability to effectively penetrate into the material to form a good mechanical embeddings, The mortar with only inorganic adhesive is not effectively bonded to it, which is well proved by electron microscope observation. The bonding mechanism of polymers is different. Polymers are bonded to the surface of other materials by intermolecular force, and do not depend on the porosity of the surface (of course, the rough surface and the increased contact surface will improve the bonding force), which is more obvious in the case of organic substrates, and the electron microscope observation has also proved its superiority in the bonding force.

The role of Redispersible Polymer Powder RDP in mortar
Redispersible emulsion powder is mainly used in internal and external wall putty powder, tile binder, tile joint agent, dry powder interface agent, external wall insulation mortar, self-leveling mortar, repair mortar, decorative mortar, waterproof mortar external insulation dry mix mortar. The purpose of the mortar is to improve the weaknesses of traditional cement mortar such as brittleness and high elastic modulus, and to provide cement mortar with better flexibility and tensile bond strength to resist and delay the formation of cracks in cement mortar. Due to the interpenetrating network structure between polymer and mortar, a continuous polymer film is formed in the pores to strengthen the bond between aggregates. Some of the pores in the mortar are blocked, so the performance of the modified mortar after hardening is greatly improved than that of the cement mortar.

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.
