What are the applications of redispersible polymer powder (RDP)?

Redispersible polymer powder (RDP) is an important polymer additive widely used in construction and industry.

1. Tile adhesives

Redispersible polymer powder acts as an adhesive enhancer in tile adhesives. It can improve bond strength, flexibility and anti-slip properties, thereby enhancing the adaptability of the adhesive to different substrates. This is especially important for the bonding of materials such as tiles, mosaics, and stones.

2. External insulation systems (EIFS)

In external insulation systems, RDP improves the adhesion between the insulation board and the base wall. It gives the system excellent crack resistance, weather resistance and flexibility, while improving the operational performance during construction. This is crucial for the durability and energy saving of the system.

3. Self-leveling mortar

As a key ingredient in self-leveling mortar, RDP can improve the fluidity, bond strength and compressive strength of the mortar. It can reduce the risk of cracking during the hardening process of the mortar and ensure a smooth surface. This is very important for high-demand ground construction such as industrial flooring and decorative flooring.

4. Waterproof mortar

In waterproof mortar, RDP improves the mortar's impermeability and bonding properties. It enhances the flexibility and durability of the mortar, can effectively prevent water penetration, and is suitable for basements, bathrooms, swimming pools and other areas that require waterproofing.

5. Putty powder

RDP improves the construction performance, bonding strength and crack resistance in putty powder. It makes putty powder easier to scrape and level during construction, and provides good surface hardness and smoothness after drying. This is very important in wall leveling and repairing.

6. Mortar modifier

Adding RDP to ordinary mortar can significantly improve the mortar's bonding performance, durability and flexibility. This enables the mortar to better adapt to different construction conditions and material requirements, such as floor leveling, plastering, masonry and other applications.

7. Repair mortar

The application of RDP in repair mortar can improve the adhesion between mortar and old substrate, increase the toughness and wear resistance of the repair layer, and ensure the long-lasting performance of the repair area. It is particularly suitable for the repair and reinforcement of concrete and stone.

8. Industrial coatings

As an additive for industrial coatings, RDP can improve the adhesion, water resistance and crack resistance of coatings and extend the service life of coatings. This plays an important role in the fields of anti-corrosion coatings and weather-resistant coatings.

9. Building glue

The application of RDP in building glue can improve the bonding strength and durability of glue, making it more suitable for pasting materials such as wood, ceramics, and glass. This glue is usually used in interior decoration, furniture manufacturing and other fields.

10. Insulation board adhesive

As used in the adhesive of insulation board, RDP can provide excellent bonding and crack resistance, ensuring a strong bond between insulation board and substrate. This is very critical in building energy saving and insulation systems.

11. Decorative mortar

The role of RDP in decorative mortar is mainly to improve the adhesion, decorative effect and durability of the mortar, making it suitable for various decorative effects, such as imitation stone, imitation brick, imitation wood, etc.

12. Interface agent

Among the interface agents, RDP can enhance the adhesion between new and old concrete or mortar layers, improve the durability and crack resistance of the interface, and is often used in concrete repair and old house renovation.

13. Other special mortars

RDP is also used in various special mortars, such as high temperature resistant mortar, acid resistant mortar, etc., to enhance its specific functionality and applicability to meet different construction environments and technical requirements.

Advantages summary
