What are the functions of redispersible latex powder in mortar?

Answer: The redispersible latex powder is dispersed and formed into a mold and acts as a second adhesive to enhance the adhesion; the protective colloid is absorbed by the mortar system (it will not be destroyed after the mold is formed. Or twice dispersed); the polymerization of the mold As a reinforcing material, the resin is distributed in the entire mortar system, thereby increasing the cohesion of the mortar.

What are the functions of redispersible latex powder in wet mortar?

Answer: Improve construction performance; improve fluidity; increase thixotropy and sag resistance; improve cohesion; extend open time; enhance water retention;

What does the redispersible latex powder do after the mortar is cured?

Answer: Improve tensile strength; increase bending strength; reduce elastic modulus; increase deformability,material compactness,wear resistance,cohesive strength; reduce carbonization depth; reduce material water absorption; make material It has excellent water repellency (adding water repellent rubber powder).

What are the effects of redispersible latex powder in different dry mortar products?

Tile adhesive

Effect on fresh mortar:
A. Extend the working time and adjustable time;
B. Improve water retention performance to ensure the splash of cement;
C. Improve sag resistance (special modified rubber powder)
D. Improve workability (easy to construct on the substrate, easy to press the tiles into the adhesive).
Effect on hardened mortar
A. It has good adhesion to various substrates, including concrete, plastering, wood, old ceramic tiles, and PVC;
B. It has good adaptability under various climatic conditions.
