Redispersible Polymer powder/RDP
1.0 What is RDP

RDP(Redispersible Polymer Powder/Redispersible Powder) or VAE is a water-soluble re-dispersible powder. It is a copolymer of ethylene and vinylacetate. It dissolves in water easily and forms emulsion quickly , RDP could offer strong adhesive and stretching force to improve the workability, flexibility and water-proofing of the materials.
This VAE Re-Dispersible Polymer Powder Used in construction uses polyvinylalcohol as a protective colloid. By adding landcel RDP, the performance of mortar with cement or gypsum can meet the needs of various constructions.

2.0 How to Choose RDP

VAE Re-Dispersible Polymer Powder (RDP)is produced by spray-drying and water-based 
emulsion, mostly based on vinylacetate and acrylicacid, dissolves in water easily and quickly 
forms emulsion.The main specification is as below, and Ash content , Film tempreture is the key properties.

3.0 How to use RDP(VAE)
Mainly used in ceramic tile adhesive, ceramic tile jointing agent, plastering gypsum, self-leveling mortar, grout material ceramic tile adhesive, bonding mortar exterior insulation system, exterior insulation system of plastering mortar, flexible interior and exterior wall putty, flexible anti-crack mortar, powder polystyrene particles insulation mortar, powder coating, insulation board, have higher request for flexible polymer mortar products.

Redispersible polymer powder product is water soluble redispersible powder, divided into ethylene/vinylacetate copolymer, with polyvinyl alcohol as a protective colloid, spray drying white powder adhesive.
This powder can be quickly dispersed into emulsion after contact with water, because of the redispersible polymer powder has high bonding capacity and unique properties, such as: water resistance, construction and heat insulation, therefore, their range of application is extremely wide.

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.

Action principle
In wet mortar to improve construction performance, improve flow performance, increase thixotropic and vertical resistance, improve cohesion, prolong opening time, enhance water retention, After curing, the tensile strength of mortar is improved, the bending strength is increased, the elastic modulus is reduced, the deformability is improved, the material density is increased, the wear-resisting strength is increased, the cohesion strength is improved, the carbonization depth is reduced, and the water absorption of the material is reduced.

Key Properties
Redispersible Polymer Powder RDP can improve adhesion,strength in bending,abrasion resistance,de-formability.It has good rheology and water retention,and can increase the sag resistance of tile adhesives,it can made up to tile adhesives with excellent non-slump properties and putty with good properties.

Benefits of HEARST products:
Better temperature stability Extended Open Time Slip Resistance Sag Resistance Delayed Hydration Improved Workability Dosage-saving Benefit with Blanced Strength & Water Retention Increased Adhension Strength
Technical data
Emulsion and RDP/Redispersible Polymer Powder(redispersible emulsion powder) can form high tensile strength and bond strength on different materials after film formation, and they are combined with inorganic binder cement as the second binder in mortar, cement and polymer play corresponding special features respectively, so that the performance of mortar can be improved. By observing the microstructure of polymer-cement composite material, it is concluded that the addition of redispersible emulsion powder can make the polymer film and become a part of the pore wall, and the mortar forms a whole through the internal force, which improves the cohesion strength of the mortar, and thus increases the failure stress and ultimate strain of the mortar. The long-term properties of redispersible emulsion powder in mortar were studied. It was observed by SEM that after 10 years, the microstructure of polymer in mortar still did not change, and it maintained stable bond, flexural and compressive strength and good hydrophobic properties. Wang Ziming et al. [11] studied the formation mechanism of the redispersible emulsion powder on the strength of the ceramic tile binder, and found that after the polymer dried into film, on the one hand, the polymer film formed a flexible connection between the mortar and the ceramic tile; on the other hand, in the newly mixed mortar, the polymer increased the gas content of the mortar and affected the formation and wettability of the surface. The polymer will also have a better effect on the hydration process and shrinkage of the cement in the binder, all of which will have a better help in improving the bond strength.

The addition of RDP/Redispersible Polymer Powder(redispersible latex powder) to mortar can significantly improve the bond strength with other materials, because the hydrophilic latex powder and the liquid phase of the cement suspension permeate into the pores and capillaries of the matrix, and the latex powder forms a film in the pores and capillaries and is firmly adsorbed on the surface of the matrix, thus ensuring a good bond strength between the cementing material and the matrix.
The optimization of latex powder on mortar performance is due to the fact that latex powder is a high polymer with polar groups. When latex powder is mixed with EPS particles, the non-polar chain segment of latex powder polymerization main chain will physically adsorb the non-polar surface of EPS. The polar groups in the polymer are oriented outward on the surface of EPS particles, making EPS particles change from hydrophobic to hydrophilic. Due to the modification effect of latex powder on the surface of EPS particles, the problem that EPS particles are easy to float when exposed to water and the stratification degree of mortar is large is solved. At this time, cement is added to mix, and the polar groups adsorbed on the surface of EPS particles interact with the cement particles and are closely combined, so that the workability of EPS insulation mortar is significantly improved. This is reflected in the EPS particles are easily wetted by cement slurry, and the binding force between the two is greatly improved.
