Properties and Uses of Redispersible Polymer Powder

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

Redispersible polymer 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 between mortar and various substrates, and improve the flexibility and deformability of mortar. Properties, compressive strength, flexural strength, wear resistance, toughness, adhesion and water retention capacity, and constructability. In addition, the hydrophobic latex powder can make the mortar very waterproof.

Redispersible polymer powder for masonry mortar and plastering mortar has good impermeability, water retention, frost resistance, and high bonding strength, which can effectively solve the problems of cracking and penetration between traditional masonry mortar and masonry question.

Self-leveling mortar, flooring material Redispersible polymer powder has high strength, good cohesion/cohesion 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 polymer 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.

Redispersible polymer powder for waterproof mortar 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. Hydrophobicity and water resistance require long-lasting effect of the sealing system.

External wall insulation mortar Redispersible polymer powder in the external wall insulation system can enhance the cohesion of the mortar and the binding force to the insulation board, and reduce 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 polymer powder has satisfactory flexibility, shrinkage, high cohesiveness, 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 polymer powder for interface mortar 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, the plaster layer is hollow, Cracking, peeling and other problems. 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.

There are a variety of Redispersible polymer powder products on the market, but their properties are basically the same, which can be briefly summarized as follows:

Redispersible polymer 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.

These products are mainly used in construction fields such as external wall insulation, tile bonding, interface treatment, bonding plaster, plastering plaster, building interior and exterior wall putty, decorative mortar, etc., and have a very wide range of use and good market prospects.

The promotion and application of Redispersible polymer 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.
