About this product

Product information from the supplier.

Redispersible Polymer Powder (RDP), also known as VAE redispersible powder, is a high-performance organic polymer additive essential for modern construction. Engineered to enhance the properties of dry-mix mortars, it is widely integrated into cement mortars, wall putties, EIFS systems, and tile bonding solutions to ensure superior structural integrity and durability.

By significantly increasing the bonding strength, flexibility, and workability of mortar, RDP prevents cracking and optimizes the coating and spreading rate. Whether used for inner wall applications or external thermal insulation, this additive provides an indispensable layer of protection and strength, ensuring that construction materials adhere perfectly to various substrates.

Frequently Asked Questions

Q: What is Redispersible Polymer Powder (RDP)?

RDP is a specialized polymer powder used in construction chemicals to improve the adhesion, flexibility, and strength of cement-based mortars and putties.

Q: How does RDP prevent cracking in wall putty?

RDP creates an elastic polymer film within the mortar matrix, allowing the material to absorb stress and movement without forming cracks.

Q: Can I use RDP in tile bonding mortar?

Yes, RDP is highly recommended for tile bonding mortar to ensure an extraordinary bond between the tile and the substrate.

Q: How can I verify the quality of RDP samples?

You can check the bonding ability by applying a solution to a tile; if the resulting film is hard to scrape off, it is qualified. Also, check for elasticity on a glass surface.

Q: Are free samples available for testing?

Yes, we provide free samples for quality verification. The buyer only needs to cover the air shipping costs.

Q: What makes RDP different from standard additives?

Unlike basic fillers, RDP provides a combination of high bonding strength, water resistance, and tensile elasticity, which are critical for modern EIFS and mortar systems.
