YAGUAN Redispersible Polymer Powder (RDP) is a high-performance emulsion powder based on ethylene-vinyl acetate copolymer. Engineered to be easily redispersed in water, this advanced additive is specifically designed to enhance the bonding strength and mechanical durability of cementitious mortars, ensuring a superior interface between the mortar and various common substrates.
By integrating RDP into polymer cement mortars, manufacturers can significantly improve anti-bending and anti-tension properties. This results in exceptional anti-crack performance and increased abrasion resistance, making it an indispensable solution for modern construction materials requiring high flexibility, strong plasticity, and long-term durability.

Frequently Asked Questions
RDP acts as a bonding agent that improves the flexibility, adhesion, and mechanical strength of cementitious mortars, preventing cracks and enhancing durability.
While HPMC primarily focuses on water retention and thickening, RDP (Redispersible Polymer Powder) focuses on increasing bonding strength, flexibility, and impact resistance.
Yes, combining RDP with Polycarboxylate Ether (PCE) allows for a synergistic effect, improving both the fluidity/workability and the final mechanical strength of the material.
Our standard RDP maintains a PH value between 6.0 and 8.0, ensuring compatibility with most alkaline cementitious environments.
By improving water retention, RDP prevents the mortar from drying too quickly, allowing workers more time to adjust and apply the material correctly.
It should be stored in a cool, dry, and well-ventilated area, away from moisture and direct sunlight to prevent premature caking or degradation.
