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.
Rdp/Redispersible powder is usually white powder, but there are a few products in other colors. The components of dispersible emulsion powder mainly include the following.
(1) Polymer resin. Polymer resin is located in the core part of rubber powder particles, and is also the main component of dispersible latex powder, such as polyvinyl acetate/vinyl resin, styrene/butadiene resin, vinyl/vinyl chloride/vinyl laurate resin, etc.
(2) Additives (inside). The additive (inside) plays a role in improving the properties of the resin. For example, a plasticizer that reduces the film forming temperature of the resin. Not every emulsion powder has additives, such as vinyl acetate/vinyl copolymer resins do not need to add plasticizers.
(3) Protective colloid. The protective colloid is a layer of hydrophilic material coated on the surface of dispersible latex powder particles. Most of the protective colloid of redispersible emulsion powder is polyvinyl alcohol.
(4) Additives (outside). In order to further improve the performance of the redispersible emulsion powder, other additives other than plasticizers are usually added, here called additives. Usually, a superplasticizer is added to the dispersible emulsion powder to improve the fluidity and dispersion of the emulsion.
(5) anti-caking agent. The anti-caking agent is usually a fine mineral filler, which acts to prevent the agglomeration of the emulsion powder during storage and transportation, and also helps the emulsion powder product to come out when it is dumped from the paper bag or tank truck.
Product Property
- HEARST-503M Rdp as a VAE polymer powder can be redispersed well into polymer emulsion again after mixing with water.
- 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.
Characteristic
