Increases Flexural and Tensile Strength:
The polymer film formed by the redispersible latex powder has excellent flexibility. It forms a film in the gaps and on the surfaces of cement mortar particles, creating flexible connections, which makes the brittle and rigid cement mortar more elastic. Mortars containing redispersible latex powder have significantly higher tensile and flexural strength compared to regular mortars.
Improves Adhesion Strength and Cohesion:
As an organic binder, the redispersible latex powder forms a high-tensile strength and adhesion strength film on various substrates. It plays a crucial role in bonding mortar with organic materials (such as EPS and extruded polystyrene foam boards) and smooth surface substrates. The polymer film formed by the latex powder acts as a reinforcing material distributed throughout the mortar system, enhancing the cohesion of the mortar.
Enhances Impact Resistance, Durability, and Abrasion Resistance:
The latex powder particles fill the pores in the mortar, increasing its density and improving abrasion resistance. Under external force, it can relax without damage. The polymer film can remain in the mortar system for a long time.
Increases Weather Resistance and Freeze-Thaw Resistance, Preventing Cracking:
Redispersible latex powder is a thermoplastic resin with excellent flexibility, enabling mortar to cope with changes in external temperature, effectively preventing cracking due to temperature variations.
Enhances Hydrophobicity and Reduces Water Absorption:
The latex powder forms a film in the pores and on the surface of the mortar, preventing water penetration and improving waterproofing. Redispersible latex powder with hydrophobic properties provides a good water-repellent effect.
Improves Workability of Mortar:
The lubricating effect between polymer powder particles allows the mortar components to flow independently. The latex powder also has an air-entraining effect, providing compressibility to the mortar and enhancing its workability.
