Application and function of redispersible polymer powder

Redispersible polymer powder is mainly used in: internal and external wall putty powder, tile adhesive, tile grout, dry powder interface agent, external thermal insulation mortar, self-leveling mortar, repair mortar, decorative mortar, waterproof mortar, etc. in dry mortar. It is a powder dispersion processed by spray drying of modified polymer emulsion. It has good redispersibility and can be re-emulsified into a stable polymer emulsion after adding water. Its chemical properties are exactly the same as the initial emulsion. . As a result, it is possible to produce high-quality dry-mix mortar, thereby improving the properties of the mortar.

Redispersible polymer powder is an indispensable and important functional additive for mixed mortar. It can improve the performance of mortar, increase the strength of mortar, improve the bonding strength of mortar and various substrates, and improve the flexibility and deformability of mortar. properties, compressive strength, flexural strength, abrasion resistance, toughness, adhesion and water retention, and constructability. In addition, the latex powder with hydrophobicity can make the mortar have good water resistance.

Redispersible latex powder has good impermeability, water retention, frost resistance, and high bonding strength, which can effectively solve the quality problems such as cracking and penetration between traditional masonry mortars.

Redispersible polymer powders have high strength, good cohesion/cohesion and required flexibility. It can improve the adhesion, wear resistance and water retention of the materials. It can bring excellent rheology, workability and better self-smoothing performance to ground self-leveling mortar and leveling mortar.

Redispersible latex powder has good cohesion, good water retention, long open time, flexibility, sag resistance and good freeze-thaw cycle resistance. Provides high adhesion, high slip resistance and good workability for tile adhesives, thin layer tile adhesives and caulks.

Redispersible latex powder enhances bonding strength to all substrates, reduces elastic modulus, increases water retention, and reduces water penetration, providing products with high flexibility, high weather resistance and high water resistance requirements. Long-lasting effect of the sealing system and waterproof requirements.

Redispersible latex powder enhances the cohesion of the mortar and the bonding force to the thermal insulation board in the external wall thermal insulation system, which can reduce energy consumption while seeking thermal insulation for you. The required workability, flexural strength and flexibility can be achieved in the external wall and external thermal insulation mortar products, so that your mortar products can have good bonding performance with a series of thermal insulation materials and base layers. At the same time, it also helps to improve impact resistance and surface crack resistance.

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

Redispersible latex powder is mainly used to treat the surfaces of concrete, air-entrained concrete, lime-sand bricks and fly ash bricks, etc., to solve the problem that the interface is not easy to bond, the plastering layer is hollow, cracked, etc. due to excessive water absorption or smoothness of these surfaces. peeling, etc. It enhances the bonding force, is not easy to fall off and is resistant to water, and has excellent freeze-thaw resistance, which has a significant effect on simple operation and convenient construction.
