In engineering construction projects, KDO redispersible polymer powder RDP is be used for different applications widely and it plays an important role in dry mix mortar field. It is used in the tile adhesives, wall putty powder and thermal insulation mortar of the buildings we live in. The addition of redispersible polymer powder RDP can increase the compactness of mortar and thus enhance its industrial indicators including tensile strength, bonding strength, etc. After the redispersible polymer powder RDP is mixed with the water in dry mortar, it will be emulsified and dispersed in water to form a stable polymer emulsion again. After emulsified and dispersed in water, the water will evaporate and form a polymer film in the mortar to improve the performance of the mortar. The redispersible polymer powder RDP has some different effects on dry powder mortar.

1. Adhesive mortar: ensure that the mortar will firmly bond the wall to the EPS board. Improve bonding strength.

2. Plastering mortar: ensure the mechanical strength of the insulation system, crack resistance and durability, and impact resistance.

3. Sealant: Make the mortar have excellent impermeability and prevent water intrusion. At the same time, it has good adhesion, low shrinkage and flexibility to the edge of the tile.

4. Wall putty for interior and exterior: improve the bonding strength of putty and ensure that the putty has a certain flexibility to buffer the different expansion and contraction stresses produced by different base layers. Ensure that the wall putty has good aging resistance, impermeability and moisture resistance.

5. Ceramic tile renovation and plastering putty: improve the adhesion and bonding strength of putty on special substrates (such as tile surface, mosaic, plywood and other smooth surfaces), and ensure that the putty has good flexibility to strain the expansion coefficient of the substrate.

6. Masonry plastering mortar: Improves water retention. Reduces water loss to porous substrates.

7. Cement-based waterproofing mortar: ensure the waterproofing performance of the mortar coating, and at the same time have good adhesion to the base surface, and improve the compressive and flexural strength of the mortar.

8. Self-leveling floor mortar: ensure the matching of the elastic modulus, bending resistance and crack resistance of the mortar. Improve the wear resistance, bonding strength and cohesion of mortar.

9. Interface mortar: improve the surface strength of the substrate and ensure the adhesion of the mortar.

10. Repair mortar: ensure that the expansion coefficient of the mortar matches the base material, and reduce the elastic modulus of the mortar. Make sure the mortar has sufficient water repellency, air permeability and cohesive force.

11. Tile Adhesive: Provides a high-strength bond to the mortar, giving the mortar enough flexibility to accommodate the different coefficients of thermal expansion of the substrate and tiles. Improve the ease of construction operation and improve work efficiency.

KDO manufacture different models of RDP which can be specialized in different application, like the flexible type, high bonding type, hydrophobic type.
