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 RDP(Redispersible polymer powder) in China.
. 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  d   issolves in water easily and forms emulsion quickly    , RDP could offer s   trong adhesive and stretching force    to  i   mprove 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.

RDP Redispersible polymer powder,VAE,Re-Dispersible polymer powder,EVA

Redispersible VAE powder HST-745W is a product made of vinyl acetate-ethylene (VAE) copolymer emulsion as the main component, via spay drying process into flowable white polymer powder, which can be widely used for dry mixed mortar or powder construction material products.

Product Description                                                                                                                                       

• HST-745W Redispersible polymer powder as a VAE polymer powder can be redispersed well into polymer emulsion again after mixing with water.
• HST-745W Redispersible polymer powder with the characteristics of middle glass transition temperature, therefore, has a good balance between adhesion and flexibility, and wide universality of application.
• HST-745W Redispersible polymer powder 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.
• HST-745W Redispersible polymer powder with good acid and alkaline resistance, is good for the workability and weatherability of the construction material products which used it.
• HST-5745W Redispersible polymer powder with good and wide compatibility, can use with almost all other chemical additives in diverse formulations.
• HST-745W Redispersible polymer powder 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.
• HST-745W Redispersible polymer powder is produced without adding plasticizer, film forming additives or solvent, so it has excellent environmental protection, low odor, low VOC.
• --Better deformability
• --Increased adhesion to a variety substrates
• --Improved wetting of the substrate
• --Higher flexural strength and flexibility
• --Increased impact and abrasion resistance
• --Higher durability and freeze thaw resistance

HST-745W RDP 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 HST-745WRDP, 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 HST-745WRDP, which can significantly reduce water absorption, improve the flexibility and bonding strength with the substrate.

Storage                                                                                                                                                                     

• HST-745W RDP storage should protect from moisture.
• At storage temperatures above 30ºC or under pressure during storage may cause HST-745W RDP caking occurs.
• If HST-745W RDP is not used up after opening, it should be sealed in time and used as soon as possible.
• The optimal service life of HST-745W is 6 montXDD, and the possibility of the product performances beyond the best use period will be reduced.
• In order to ensure the best use effect of HST-745W, it is recommended to test the product's performances before use.
