Product Description
| High Strength Vae Redispersible Polymer Powder for Readymix Mortar |
Redispersible VAE powder HST-328 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.
Redispersible Polymer Powder
328
Produced by spray-drying special water-based emulsion. Mostly based on vinyl acetate-ethylene. Dissolves in water easily and quickly forms emulsion. Its chemical properties are the same as original emulsion competely. Excellent flexibility in low temperature.
It can glue together different substrates, reinforce mortar struture and provide excellent adhesion at cement or gypsum based dry mixed mortar substate interface.Physical Properties:Redispersible Polymer Powder is widely used in construction areas especially used in construction mortar. Throughout the mortar system and increase mortar cohesion. Powder Material with Green Environment Protection. Welcome to contact me and get long time cooperation
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.
Product Description
- HST-328 RDP as a VAE polymer powder can be redispersed well into polymer emulsion again after mixing with water.
- HST-328 RDP with the characteristics of middle glass transition temperature, therefore, has a good balance between adhesion and flexibility, and wide universality of application.
- HST-328 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.
- HST-328 RDP with good acid and alkaline resistance, is good for the workability and weatherability of the construction material products which used it.
- HST-328 RDP with good and wide compatibility, can use with almost all other chemical additives in diverse formulations.
- HST-328 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.
- HST-328 RDP is produced without adding plasticizer, film forming additives or solvent, so it has excellent environmental protection, low odor, low VOC.

HST-328 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-328, 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-328, which can significantly reduce water absorption, improve the flexibility and bonding strength with the substrate.
Application range
- Tile adhesive/Tile grouts/tile joint filler
- Tile renovation interface agent
- Skim coat (Putty)/wall putty/Dry putty powder
- EIFS system mortar/coating mortar for EIFS(external insulation finish system)
- EIFS system mortar/adhesive mortar for EIFS(external insulation finish system)
- Thermal insulation mortar
- decoration mortar
- dry mixed mortar
- Surface modification cement
- Powder latex paint
- Thermal insulation building materials
- Self-leveling mortar
Characteristic
--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
Storage
- Ensure that the packaging is intact during transportation, protects from moisture, avoids high temperature and pressure.
- HST-328 storage should protect from moisture.
- At storage temperatures above 30ºC or under pressure during storage may cause HST-328 caking occurs.
- If HST-328 is not used up after opening, it should be sealed in time and used as soon as possible.
- The optimal service life of HST-328 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-328, it is recommended to test the product's performances before use.
