Redispersible Polymer Powder (RDP) is a water-soluble, white or off-white free-flowing powder. It exhibits high adhesive strength and outstanding waterproof properties. RDP enhances the elasticity of mortar, extends open time, and improves adhesion, flexural strength, plasticity, abrasion resistance, and workability. It is particularly beneficial for flexible anti-crack mortars due to its high flexibility and wide range of applications.

Applications

RDP can be used in various dry-mix mortars, including:
- Interior and exterior wall putty powder
- Tile adhesives
- Tile grouts
- Dry powder interface agents
- Exterior wall insulation mortars
- Self-leveling mortars
- Repair mortars
- Decorative mortars
- Waterproof mortars

Product Advantages

1. Enhanced Impact Resistance, Durability, and Abrasion Resistance:
  - RDP particles fill the cavities in the mortar, increasing its density and abrasion resistance. Under external force, the mortar relaxes rather than breaking. The polymer film can persist in the mortar system for extended periods.

2. Improved Workability:
  - The lubricating effect between polymer powder particles allows mortar components to flow independently. Additionally, the powder induces air, providing compressibility and improving workability.

3. Increased Adhesive Strength and Cohesion:
  - As an organic adhesive, RDP forms a film that provides high tensile and adhesive strength on various substrates. It significantly enhances the bond between mortar and organic materials (like molding boards, extrusion boards) or smooth surfaces. The polymer film distributes throughout the mortar system, enhancing its cohesion.

4. Enhanced Weather Resistance, Freeze-Thaw Resistance, and Crack Prevention:
  - Being a thermoplastic resin powder, RDP adds flexibility to the mortar, allowing it to withstand temperature changes without cracking.

5. Improved Hydrophobicity and Reduced Water Absorption:
  - RDP forms a polymer film in the cavities and on the surface of the mortar, which does not re-disperse in water, thus preventing water penetration and enhancing water resistance. Hydrophobic RDP enhances the water-repellent properties of the mortar.

6. Increased Flexural Strength and Flexibility:
  - The polymer film formed by RDP is highly flexible, filling the gaps and coating the surfaces of cement particles, creating a flexible connection. This converts the brittle cement mortar into an elastic material. Mortars containing RDP exhibit superior tensile and flexural strength compared to regular mortars.
