Properties and uses of redispersible powder

November 19, 2021by admin0

Redispersible latex powder is a powdery dispersion made of modified polymer polymer emulsion by spray drying. It has good dispersibility and can be re-emulsified into a stable polymer emulsion after adding water. The performance is exactly the same as the initial emulsion. Therefore, it becomes possible to produce high-quality dry-mixed mortar, thereby improving the properties of the mortar.

Redispersible latex powder is an essential and important functional additive for mortar. It can improve the performance of mortar, increase the strength of mortar, improve the bonding strength of mortar to various substrates, and improve the flexibility and deformability of mortar Resistance, compressive strength, flexural strength, abrasion resistance, toughness, adhesion and water retention capacity, workability. In addition, the latex powder with hydrophobic properties can make the mortar very waterproof.

Redispersible latex powder for masonry mortar and plastering mortar has good impermeability, water retention and freeze resistance, and high bonding strength, which can effectively solve the cracking and infiltration quality existing in traditional masonry mortar. problem.

Self-levelling mortar and floor material Redispersible latex powder has high strength, good cohesion / adhesion and required flexibility. Can improve the adhesion, abrasion resistance and water retention of the materials. It can bring excellent rheology, workability and best self-smoothing performance to floor self-leveling mortar and screed.

Tile adhesive, tile jointing agent Redispersible latex powder has good adhesion, good water retention, long open time, flexibility, sag resistance and good freeze-thaw resistance. It can bring high adhesiveness, high slip resistance and good construction operability to tile adhesive, thin-layer tile adhesive and joint filler.

Waterproof mortar redispersible latex powder enhances the bond strength to all substrates, reduces elastic modulus, increases water retention, reduces water penetration, and provides products with high flexibility, weather resistance and high water resistance Watertightness and water resistance require a long-lasting effect of the sealing system.

External wall external insulation mortar Redispersible emulsion powder in the external wall external insulation system enhances the cohesion of the mortar and the binding force to the thermal insulation board, so that you can seek insulation and reduce energy consumption. To achieve the necessary workability, flexural strength and flexibility in external wall insulation mortar products, you can make your mortar products have a good bonding performance with a series of insulation materials and the base. At the same time, it also helps to improve the impact resistance and surface crack resistance.

Repair Mortar Redispersible latex powder has the required flexibility, shrinkage, high cohesion, suitable flexural and tensile strength. Make repair mortar meet the above requirements for repair of structural and non-structural concrete.

Interfacial mortar redispersible latex powder is mainly used to treat the surface of concrete, aerated concrete, lime sand brick and fly ash brick. Cracking, peeling, etc. It makes the adhesion stronger, not easy to fall off and water resistance, and excellent freeze-thaw resistance. It has a significant effect on simple operation, convenient construction.
