Performance of redispersible latex powder products:
1. Enhance the flexural strength and bending resistance of mortar
The polymer film formed by redispersible latex powder exhibits excellent flexibility. It forms a film within the voids and on the surface of cement mortar particles, creating a flexible bond that imparts elasticity to the otherwise brittle and rigid cement mortar. Mortar incorporating redispersible latex powder demonstrates tensile and flexural strengths several times greater than those of conventional mortar.
2. Enhance the bond strength and cohesion of the mortar
Redispersible latex powder, when used as an organic binder, forms a film that exhibits high tensile strength and adhesion on various substrates. It plays a crucial role in enhancing the bond between mortar and organic materials such as EPS (expanded polystyrene) and smooth-surfaced substrates. The polymer film-forming binder is dispersed throughout the mortar matrix as a reinforcing agent, thereby increasing the mortar’s cohesion.
3. Enhance the mortar’s impact resistance, durability, and wear resistance.
The rubber powder particles fill the voids in the mortar, increasing its density and enhancing its wear resistance. Under external loading, the material exhibits creep without fracturing. The polymer film coating can remain permanently within the mortar matrix.
4. Enhance the mortar’s weather resistance and freeze-thaw durability to prevent cracking.
Redispersible latex powder is a thermoplastic resin with excellent flexibility, enabling mortar to withstand external temperature fluctuations and effectively preventing cracking caused by thermal expansion and contraction.
5. Enhance the hydrophobicity of the mortar and reduce its water absorption.
Redispersible latex powder forms a film within the pores and on the surface of mortar; once exposed to water, the polymer film does not redisperse, thereby preventing water penetration and enhancing impermeability. Special redispersible latex powders with hydrophobic properties deliver even better water-repellent performance.
6. Enhance the workability of mortar during construction
Polymer latex powder particles exhibit a lubricating effect, enabling the mortar constituents to flow independently; at the same time, the latex powder exerts an air-entraining effect, imparting compressibility to the mortar and enhancing its workability and ease of placement.
