Product Description

Shandong Hearst Building Material Co.,ltd
We have strong financial strength, and introduced full set of production line with industry leading level from German. With foreign advanced technology production base and our research and development center, annual output of 22000tons,now we have become one of the biggest and trusted manufacturer of Redispersible polymer powder in China.
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 adhesive powder 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.
Rdp/Redispersible emulsion 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.
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
