Product Description
| Customization Cement Additive Rdp Powder Redispersible Polymer Powder Cetate Ethyl Comopolymer Powder |
Redispersible VAE powder HEARST-503M 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 503M
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
- 503M RDP as a VAE polymer powder can be redispersed well into polymer emulsion again after mixing with water.
- 503M RDP with the characteristics of middle glass transition temperature, therefore, has a good balance between adhesion and flexibility, and wide universality of application.
- 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.
- 503M RDP with good acid and alkaline resistance, is good for the workability and weatherability of the construction material products which used it.
- 503M RDP with good and wide compatibility, can use with almost all other chemical additives in diverse formulations.
- 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.
- 503M RDP is produced without adding plasticizer, film forming additives or solvent, so it has excellent environmental protection, low odor, low VOC.

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 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 503M, 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.
- 503M storage should protect from moisture.
- At storage temperatures above 30ºC or under pressure during storage may cause 503M caking occurs.
- If 503M is not used up after opening, it should be sealed in time and used as soon as possible.
- The optimal service life of 503M 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 503M, it is recommended to test the product's performances before use.
Packaging
- 25Kg bag
- 600Kg Big Bag
- Standard packing: 25kg/bag inner with PE bags
1*20'FCL: 14 tons with pallets or 17 tons without pallet
