YAGUAN Redispersible Polymer Powder (RDP) is a high-performance emulsion powder derived from ethylene-vinyl acetate copolymer. Engineered to be fully redispersible in water, this advanced additive significantly enhances the bonding strength between mortar and common substrates, ensuring superior mechanical performance and structural integrity for modern construction materials.
By incorporating RDP into polymer cement mortars, manufacturers can achieve exceptional anti-bending and anti-tension properties. This results in a material with outstanding anti-crack performance, effectively preventing structural fissures while improving the overall flexibility, plasticity, and abrasion resistance of the final application.

Frequently Asked Questions
RDP acts as a redispersible polymer that improves the adhesive strength, flexibility, and water resistance of cement-based mortars, preventing cracks and enhancing mechanical performance.
It optimizes the rheological properties of the mix, providing better slip resistance and a smoother application process, which improves overall labor efficiency.
Yes, RDP is frequently used alongside HPMC. While HPMC provides water retention and thickening, RDP provides the necessary adhesive strength and flexibility.
By reducing water uptake and preventing cracks through enhanced flexural strength, RDP significantly extends the service life of tiles, facades, and structural mortars.
It should be stored in a cool, dry, and well-ventilated area, away from moisture and direct sunlight to ensure it remains redispersible.
Professional grade RDP, such as YAGUAN's, typically maintains a solid content of 98% or higher to ensure maximum efficiency in the mortar mix.
