What is dispersible polymer powder?

Dispersible polymer powder(RDP powder, VAE powder) is a white powdery polymer commonly used to modify cement-based or gypsum-based mortars.

Vinyl acetate-ethylene re-dispersible powder can be quickly redispersed into an emulsion after meeting water and has the same properties as the initial emulsion; that is, as the water evaporates during the coagulation and hardening of the cement mortar, the polymer particles are in the cement mortar. A film is formed, which acts like a polymer emulsion to modify the cement mortar. This film has high flexibility, weather resistance, abrasion resistance, and good adhesion to various substrates.

Redispersible polymer powder uses:

Redispersible polymer powder can improve construction performance; 

Redispersible polymer powder can improve flow performance, increase thixotropy and sag resistance; 

Redispersible polymer powder can improve cohesion, extend open time, and enhance water retention.

The effect of VAE Redispersible polymer powder can be after the mortar is cured.

Increase tensile strength; increase bending strength; reduce elastic modulus; improve deformability; increase material compactness; increase wear resistance; increase cohesive strength; reduce carbonization depth; reduce material water absorption; make materials have excellent water-increasing (adding water-increasing rubber powder).

Function in wet mortar

The effect of mortar curing

Improve tensile strength; Increase bending strength; Reduce the elastic modulus; Improve deformability; Increase the density of the material; Increase wear resistance; Improve cohesion strength; Reduce the carbonization depth; Reduce material water absorption; Make the material have excellent water increase (add water increase rubber powder)

Self-leveling mortars, floor materials: Emulsion powder with high strength, good cohesion/bonding and the required flexibility. It can improve the materials' adhesion, wear resistance and water retention—excellent rheology, construction and self-smoothing for ground self-leveling mortar and screed mortar.

Ceramic tile binder, ceramic tile joint agent: emulsion powder has good adhesion, water retention, long opening time, flexibility, anti-sagging performance and good anti-freeze-thaw cycle ability. It can bring high adhesion, high slip resistance and good construction operability for tile adhesives, thin layer tile adhesives and caulking agents.

Waterproof mortar: The emulsion powder enhances the bond strength of all substrates, reduces the elastic modulus, increases water-retention, reduces water penetration, and provides a durable effect of the sealing system with hydrophobic and waterproof requirements for products with high flexibility, high-weather resistance and high water resistance requirements.

External wall insulation mortar: Latex powder in the exterior wall insulation system enhances the mortar's cohesion and the insulation board's binding force, allowing you to seek insulation while reducing energy consumption. The external insulation mortar products achieve the necessary workability and flexibility, which can make your mortar products have good bonding properties with a series of insulation materials and the base. At the same time, it also helps improve the impact and surface cracking resistance.

Repair mortar: emulsion powder has the required flexibility, shrinkage, high adhesion, suitable bending and tensile strength. The repair mortar can meet the above requirements and repair structural and non-structural concrete.

Interface mortar: Emulsion powder is mainly used to treat the surface of concrete, aerated concrete, lime sand brick and fly ash brick.

Packaging and storage of Redispersible polymer powder 

Redispersible polymer powder should be stored in a cool and dry place. The recommended period of use is six months. 

Please use re-dispersible powder as early as possible when used in summer. 

If stored in a hot and humid place, dispersible powder will increase the chance of agglomeration. 

Please use re-dispersible powder as much as possible after opening the bag. 

Paper-plastic compound square bottom valve bag, 25kg/bag.
