Redispersible latex powder is a powder formed after spray drying of polymer emulsion, also known as dry powder glue. This powder can quickly revert to an emulsion after contacting with water, and maintain the same properties as the initial emulsion, that is, a film will be formed after the water evaporates. This film has high flexibility, high weather resistance and resistance to various substrates. High bond line.
Redispersible latex powder is mainly used in construction fields such as external wall insulation, tile bonding, interface treatment, bonding gypsum, plastering plaster, building interior and exterior wall putty, decorative mortar, etc. It has a very wide range of use and a good market prospect.
The promotion and application of redispersible latex powder has greatly improved the performance of traditional building materials, and greatly improved the adhesion, cohesion, flexural strength, impact resistance, wear resistance, durability, etc. of building material products, thus The construction products ensure the quality of construction projects with their excellent quality and high-tech content.
Application of redispersible latex powder:
◆Masonry mortar, plastering mortar: Redispersible latex powder has good impermeability, water retention, frost resistance, and high bonding strength, which can effectively solve the cracking and penetration between traditional masonry mortar masonry and other quality issues.
◆Self-leveling mortar and floor materials: Redispersible latex powder has high strength, good cohesion, cohesiveness and required flexibility. It can improve the adhesion, wear resistance and water retention of the matched materials. It can bring excellent rheology, workability and best self-smoothing performance to ground self-leveling mortar and leveling mortar.
◆Tile Adhesive, Tile Pointing Agent: Redispersible latex powder has good cohesiveness, good water retention, long open time, flexibility, sagging resistance and good freeze-thaw cycle resistance. Provides high adhesion, high slip resistance and good application handling for tile adhesives, thin layer tile adhesives and caulks.
◆Waterproof mortar: Redispersible latex powder enhances the bonding strength to all substrates, reduces elastic modulus, increases water retention, and reduces water penetration. It provides products with high flexibility, high weather resistance and high water resistance requirements. It ensures the long-lasting effect of the sealing system with hydrophobic and waterproof requirements.
◆External wall insulation mortar: Redispersible latex powder in the external wall insulation system enhances the cohesion of the mortar and the binding force to the insulation board, and reduces energy consumption while seeking insulation for you. The external thermal insulation mortar products of external walls can achieve the necessary workability, flexural strength and flexibility, which can make your mortar products 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.
◆ Repair mortar: Redispersible latex powder has satisfactory flexibility, shrinkage, high cohesiveness, and 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.
◆ Interface mortar: Redispersible latex powder is mainly used to treat the surface of concrete, aerated concrete, lime-sand brick and fly ash brick, etc., to solve the problem that the interface is not easy to bond and the plaster layer is empty due to the strong water absorption or smoothness of these surfaces. Drumming, cracking, peeling and other issues. It makes the bonding strength stronger, not easy to fall off and resistant to water, and has excellent freeze-thaw resistance, which has a significant effect on simple operation and convenient construction.
