Ethylene-vinyl acetate copolymer redispersible polymer powder, also known as VAE, is a white, free-flowing powder created by spray-drying an EVA emulsion. This powder readily re-emulsifies and disperses in water, forming a stable emulsion. While retaining the excellent properties of the original EVA emulsion, its unique powder form offers the added benefits of convenience and reliability in handling and storage.

In Dry Mortar Application of Redispersible Polymer Powder (RDP JF1)

  • External wall thermal insulation mortar: latex powder in the external thermal insulation system of the external wall enhances the cohesion of the mortar and the binding force to the thermal insulation board, and reduces energy consumption while seeking thermal insulation for you. The external thermal insulation mortar products of external walls can achieve the necessary workability, flexural strength and flexibility, which can make your mortar products have good bonding performance with a series of thermal insulation materials and base layers. At the same time, it also helps to improve impact resistance and surface crack resistance.

  • Tile adhesive, tile jointing agent: latex powder has good cohesiveness, good water retention, long open time, flexibility, sagging resistance and good freeze-thaw cycle resistance. Provides high adhesion, high slip resistance and good application handling for tile adhesives, thin layer tile adhesives and caulks.

  • Waterproof mortar: Latex powder enhances the bonding strength to all substrates, reduces elastic modulus, increases water retention, and reduces water penetration. It provides products with high flexibility, high weather resistance and high water resistance. Long-lasting effect of sealing system for water and water resistance requirements.

  • Repair mortar: Latex powder has satisfactory flexibility, shrinkage, high cohesion, and suitable flexural and tensile strength. Make the repair mortar meet the above requirements and be used for the repair of structural and non-structural concrete.

  • Interface mortar: Latex powder is mainly used to treat the surface of concrete, aerated concrete, lime-sand brick and fly ash brick, etc., to solve the problem that the interface is not easy to bond, the plaster layer is hollow, and cracking due to the excessive water absorption or smoothness of these surfaces , Peeling and other issues. It makes the bonding strength stronger, not easy to fall off and resistant to water, and has excellent freeze-thaw resistance, which has a significant effect on simple operation and convenient construction.

  • Masonry mortar, plastering mortar: latex powder has good impermeability, water retention, frost resistance, and high bonding strength, which can effectively solve the quality problems such as cracking and penetration between traditional masonry mortar masonry .

  • Self-leveling mortar and floor materials: latex powder has high strength, good cohesion/cohesion and required flexibility. It can improve the adhesion, wear resistance and water retention of the matched materials. It can bring excellent rheology, workability and best self-smoothing performance to ground self-leveling mortar and leveling mortar.

  • Decorative mortar: Latex powder can improve the adhesion of all substrates and improve the quality of mortar, prolonging the service life of decorative mortar and plastering.
