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.
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.

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.
