RDP/VAE(Redispersible Polymer Powder/Redispersible Powder)
RDP (Redispersible Polymer Powder/Redispersible Powder) or VAE is a water-soluble re-dispersible powder. It is a copolymer of ethylene and vinyl acetate. 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. Redispersible Polymer Powder is a kind of free-flowing white powder,which is spray-dryed by polymer emulsion and after subsequent treatment to keep the stability of powder appearance and character. The mainly application is in construction dry-mixed mortar,and have excellent performance in increasing the dry mortar cohesion,adhesion and flexibility.
The redispersible polymer powder(VAE) is a water-soluble re-dispersible powder. It is a copolymer of ethylene and vinyl acetate. It uses polyvinyl alcohol as a protective colloid. By adding re-dispersible latex powder, the performance of mortar with cement or gypsum as the substrate can meet the needs of various constructions.
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.

- HEARST-503M Rdp with the characteristics of middle glass transition temperature, therefore, has a good balance between adhesion and flexibility, and wide universality of application.
- HEARST-503M Rdp can form film with suitable hardness inside and surface of the finished construction material product, which can significantly improve the cohesion, wear resistance, impact resistance and waterproofing ability.
- HEARST-503M Rdp with good acid and alkaline resistance, is good for the workability and weatherability of the construction material products which used it.
- HEARST-503M Rdp with good and wide compatibility, can use with almost all other chemical additives in diverse formulations.
- HEARST-503M Rdp not only retains the superior performances of the original VAE emulsion, such as good film formation, excellent adhesion and durable flexibility, but also improves the convenience and stability for transportation, storage and operation.
- HEARST-503M Rdp is produced without adding plasticizer, film forming additives or solvent, so it has excellent environmental protection, low odor, low VOC.

Applications and dosage
HEARST-503M is recommended to use in dry mixing mortar or powder construction material products, such as ceramic tile adhesive, tile grout, external wall insulation system (EIFS/ETICS), extrusion mortar for EPS component, waterproofing mortar, self-leveling mortar, repair mortar, decorative mortar, skim coat, fire-resistant mortar, sound insulation mortar, Joint compound, AAC adhesive, gypsum products, etc.
Normally recommended dosage is 0.5~5% in total formulation.

- In EIFS/ETICS formulation, is recommended to add 2~4% dosage of HEARST-503M, which can effectively improve the bonding strength, impact resistance and reduce water absorption.
- In skim coat formulation, is recommended to add 1~5% dosage of HEARST-503M, which can significantly reduce water absorption, improve the flexibility and bonding strength with the substrate.

Redispersible polymer powder(RDP/VAE) can be redispersed into emulsions quickly after contact with water. Due to their high binding ability and unique properties. Such as water resistance, workability and heat insulation. they are range of applications that is extremely wide.
The role of redispersible emulsion powder in mortar
There is a suitable amount of redispersible adhesive powder, which can improve the performance of mortar and save the cost.Preliminary test: Ash according to the standard requirements EVA emulsion rubber powder should be 12%; The difference in vitrification temperature can be applied in different fields:
Theoretically speaking, the product itself of the rubber powder with a glass conversion temperature below 5 ° C is more flexible, and it is mainly used in external insulation mortar.
A glass transition temperature above 10ºC adhesive powder is mainly used in adhesives and self-leveling mortar.
Depending on the composition of the mortar, the application performance of the mortar will also be affected by the change in the amount of redispersible rubber powder added:
. The addition of redispersible adhesive powder < 1% has a certain influence on the constructability and cohesiveness of mortar;
. The addition amount of redispersible rubber powder is 1-2.0% to improve the strength, water resistance and flexibility of mortar;
. The amount of redispersible glue powder is 2.0-5%, forming a network polymer film in the mortar, which significantly improves the strength and flexibility of the mortar under different climates and interfaces;
A different lime sand ratio will have a great impact on the properties of mortar, especially the mechanical properties. The preparation of mortar must first ensure that it has good workability and constructability.
The demand for cement paste depends on the porosity of the sand and the size of the total surface, if the number of cement paste is insufficient, it is difficult to ensure the performance of the mortar."
If you blindly increase the amount of cement, it will not only increase the cost, but also make the mortar shrink and increase, and even cause building cracks.
Therefore, the determination of the lime sand ratio should consider the performance and economic factors. In order to determine the appropriate ratio of lime to sand, the test material is construction sand, adding 2% of redispersible rubber powder and 0.2% of cellulose ether.
