Product Description

Product Description                                                                                                                                               

Factory Outlet Skim coat (Putty) Rdp Powder Redispersible Polymer

RDP/VAE(Redispersible Polymer Powder/Redispersible Powder)
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.
Redispersible Polymer Powder (RDP) is spray dried re-dispersible polymer emulsion latex powder, designed for the construction industry to enhance the properties of dry mortar blends, able to Redispersible in water and react with hydrate product of cement / gypsum and stuffing, form composite membrane with good mechanics intensity. It improves the important application properties of dry mortars, like longer opening time, better adhesion with difficult substrates, lower water consumption.
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.

• HST-503M as a VAE polymer powder can be redispersed well into polymer emulsion again after mixing with water.
• HST-503M with the characteristics of middle glass transition temperature, therefore, has a good balance between adhesion and flexibility, and wide universality of application.
• HST-503M 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-503M with good acid and alkaline resistance, is good for the workability and weatherability of the construction material products which used it.
• HST-503M with good and wide compatibility, can use with almost all other chemical additives in diverse formulations.
• HST-503M 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-503M is produced without adding plasticizer, film forming additives or solvent, so it has excellent environmental protection, low odor, low VOC.
  Properties:
• 1. It can improve its adhesion, flexural strength, abrasion resistance and workability.
• 2. High flexibility and good bonding strength.
  3. It has extremely outstanding waterproof performance.
  4. Increase the elasticity of the mortar and have a longer open time.
  5. Give the mortar excellent alkali resistance.
  Redispersible Polymer Powder RDP can improve adhesion,strength in bending,abrasion resistance,de-formability.It has good rheology and water retention,and can increase the sag resistance of tile adhesives,it can made up to tile adhesives with excellent non-slump properties and putty with good properties.

HST-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 HST-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 HST-503M, which can significantly reduce water absorption, improve the flexibility and bonding strength with the substrate.
