The role of VAE Re-dispersible Polymer Powder in mortar

1. Improve the compressive strength and flexural strength of mortar.

2. The addition of VAE Re-dispersible Polymer Powder improves the elongation of mortar, thus improving the impact toughness of mortar, and also endows the mortar with good stress dispersion.

3. The adhesive property of mortar is improved. The bonding mechanism is based on the adsorption and diffusion of macromolecules on the adhesive surface, and the adhesive powder has certain permeability, which is filled with cellulose ether

Partially wet the surface of the base course material, so that the surface performance of the base course is close to that of the new plastering, thus improving the adsorption and greatly increasing its performance.

4. VAE Re-dispersible Polymer Powder reduces the elastic modulus of mortar, improves the deformation ability and reduces cracking.

5. Improve the abrasion resistance of mortar. The improvement of abrasion resistance is mainly due to the presence of a certain amount of rubber particles on the surface of mortar, the adhesive powder plays a bonding role, and the rubber powder forms a network film

The structure can pass through the holes and cracks in the cement mortar. The adhesion between the base material and the cement hydration product is improved, thus improving the wear resistance.

6. VAE Re-dispersible Polymer Powder endows mortar with excellent alkali resistance.
