The RDP powder is a water-soluble redispersible powder, which is a copolymer of ethylene and vinyl acetate, and uses polyvinyl alcohol as a protective colloid. Due to the high bonding ability and unique properties of redispersible latex powder, such as water resistance, workability, and thermal insulation, their application range is extremely wide. Redispersible latex powder is mainly used in various dry mixed mortars such as putty powder for internal and external walls, ceramic tile bonding agent, ceramic tile pointing agent, dry powder interface agent, external wall insulation mortar, self leveling mortar, repair mortar, decorative mortar, waterproof mortar, etc. Redispersible latex powder is a green, environmentally friendly, energy-saving, high-quality and versatile powder building material, and is an essential functional additive for dry mixed mortar. It can improve the performance of mortar, increase its strength, enhance the bonding strength between mortar and various substrates, enhance the flexibility and variability, compressive strength, flexural strength, wear resistance, toughness, adhesion and water retention capacity, and constructability of mortar. In addition, latex powder with hydrophobicity can make the mortar have good waterproof properties.
The role of redispersible latex powder:
1. The EVA copolymer forms a film after dispersion and serves as the second adhesive to enhance its strength;
2. The protective colloid is absorbed by the mortar system (it will not be damaged by water after film formation, or “secondary dispersion”;
3. The film-forming polymer resin is distributed as a reinforcing material throughout the entire mortar system, thereby increasing the cohesion of the mortar; Redispersible emulsion powder is a kind of powder adhesive made by special lotion (high polymer) after spray drying. After contacting with water, this powder can be quickly re dispersed to form lotion, and has the same properties as the initial lotion, that is, the water can form a film after evaporation. This film has high flexibility, high weather resistance and high adhesion to various substrates.
The Function and Application of Redispersible Latex Powder
Redispersible emulsion powder is a kind of powder adhesive made by special lotion (high polymer) after spray drying.

High strength RDP is a green, environmentally friendly, energy-saving, high-quality and versatile powder building material, and is an essential functional additive for dry mixed mortar. It can improve the performance of mortar, increase its strength, enhance the bonding strength between mortar and various substrates, enhance the flexibility and variability, compressive strength, flexural strength, wear resistance, toughness, adhesion and water retention capacity, and constructability of mortar. In addition, latex powder with hydrophobicity can make the mortar have good waterproof properties.
Redispersible latex powder is mainly used in various dry mixed mortars such as putty powder for internal and external walls, ceramic tile bonding agent, ceramic tile pointing agent, dry powder interface agent, external wall insulation mortar, self leveling mortar, repair mortar, decorative mortar, waterproof mortar, etc.
Scope of use
1. External wall insulation and plastering mortar
2. Ceramic tile pointing agent
3. Flexible putty for exterior walls
This product is a soft latex powder that can be dispersed in water, improving the adhesion between mortar and ordinary supports, improving the mechanical properties of mortar, and enhancing its constructability.
