About this product

Product information from the supplier.

Redispersible Polymer Powder (RDP), often referred to as VAE powder, is a high-performance additive essential for modern construction chemistry. Specially engineered to be redispersible in water, this polymer powder is widely integrated into cement-based mortars, wall putties, and tile adhesives to significantly enhance bonding strength and structural integrity.

By optimizing the coating and spreading rates of mortars, RDP ensures a smooth application while providing critical anti-cracking properties. Whether used in EIFS mortar, inner wall mortar, or tile seam filling, our RDP delivers extraordinary adhesion and durability, making it an indispensable component for achieving professional-grade construction standards.

Frequently Asked Questions

Q: What is RDP and how is it used in construction?

RDP (Redispersible Polymer Powder) is a water-soluble polymer additive used in dry-mix mortars. It is mixed into cement-based products like tile adhesives and wall putties to improve adhesion, flexibility, and strength.

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

A simple method is to apply an RDP solution to a clean tile surface. Once dried, it should form a film that is very difficult to scrape off, indicating high bonding quality.

Q: Does RDP help in preventing cracks in wall putty?

Yes, RDP enhances the elasticity and tensile strength of the structure, which significantly reduces the risk of shrinkage cracks and improves overall durability.

Q: Can I get free samples before placing a bulk order?

Absolutely. We provide free samples to ensure quality satisfaction. The buyer only needs to cover the air shipping costs.

Q: How is the dispersibility of the powder tested?

By pouring an RDP solution onto glass; once dried, it should form a smooth, even layer of film that is elastic and tensile when stretched.

Q: In which construction products is RDP most effective?

It is highly effective in tile bonding mortars, EIFS (External Insulation and Finish Systems), inner wall mortars, and tile seam fillers.
