JF REDISPERSIBLE POLYMER POWDER Product Introduce:
RDP (Redispersible Polymer Powder/Redispersible Powder) or VAE is a water-soluble redispersible powder. It is a copolymer of ethylene and vinyl acetate. Easily soluble in water and quickly forming an emulsion, RDP can provide strong adhesion and tensile force, improving the material's workability, flexibility and waterproofness.
This VAE redispersible polymer powder for construction from JUFU uses polyvinyl alcohol as a protective colloid. By adding JUFU RDP, the performance of cement or gypsum mortar can meet the needs of various constructions.

Application Of Redispersible Polymer Powder:
Inside and outside wall putty powder, ceramic tile adhesive, ceramic tile joint agent, dry powder interface agent, exterior insulation mortar, self-leveling mortar, repair mortar, decorative mortar, waterproof mortar and exterior insulation dry mix mortar. In mortar, it is to improve the brittleness and high elastic modulus of traditional cement mortar, give cement mortar better flexibility and tensile bond strength, in order to resist and delay the crack of cement mortar.
As the polymer and mortar form a network structure of mutual permeability, the continuous polymer film is formed in the pores, which enhances the bond between aggregates and blocks some pores in the mortar. Therefore, the performance of hardened modified mortar is better than cement mortar. There's been a lot of progress.
The Role Of Redispersible Polymer Powder In Mortar:
1. Improve the compressive strength and flexural strength of mortar.
2. The addition of latex powder increases the elongation of mortar, thus improving the impact toughness of mortar, but also gives a good stress dispersion effect of mortar.
3. Improve the bonding performance of mortar. The bonding mechanism depends on the adsorption and diffusion of macromolecules on the bonding surface. At the same time, the rubber powder has a certain air permeability. Together with cellulose ether, it can fully penetrate the substrate surface, so that the substrate layer and the surface performance of the new gypsum close, thus improving the adsorption capacity, greatly improve its performance.
4. Reduce the elastic modulus of mortar, improve the deformation ability, reduce cracking phenomenon.
5. Improve the wear resistance of mortar. The improvement of wear resistance is mainly due to the presence of a certain amount of glue on the surface of mortar. Rubber powder acts as a bond. The omental structure formed by rubber powder can pass through holes and cracks in cement mortar. Improve the bond between the base material and cement hydration products, thereby increasing wear resistance.
6. The mortar has excellent alkali resistance.
