High-Performance Redispersible Polymer Powder (RDP) with Bond Strength Comparable to Leading International Brands, Delivering Excellent Adhesion, Flexibility, Water Resistance, Smooth Workability, and Outstanding UV Aging Resistance for Tile Adhesive, Wall Putty, Self-Leveling Mortar, EIFS, and Dry Mix Mortar Applications. Stable Quality and Reliable Global Supply for Construction Chemical Buyers.
Products Description
Redispersible Polymer Powder (RDP) is a free-flowing white powder produced by spray drying specially modified polymer emulsions. When mixed with water, it can rapidly redisperse and reform a stable emulsion, providing excellent bonding, flexibility, water resistance, and workability for cement-based and gypsum-based dry mix mortars.
Our VAE-based Redispersible Polymer Powder is widely used in tile adhesive, wall putty, self-leveling mortar, EIFS/ETICS systems, repair mortar, skim coat, gypsum products, and waterproof mortar applications.

Main Features & Benefits of RDP
Excellent Adhesion Strength
RDP forms a polymer film between cement hydration products and substrate interfaces, significantly improving bonding strength and reducing cracking risks.
Improved Flexibility & Deformation Resistance
The polymer film has low elastic modulus, helping mortar absorb stress and bridge micro-cracks, thereby enhancing flexibility and deformation capability.
Enhanced Water Resistance
Our VAE Redispersible Polymer Powder improves water resistance, weather resistance, and durability in humid and outdoor environments.
Better Workability
RDP improves mortar smoothness, consistency, anti-sagging performance, and construction efficiency during application.
Crack Resistance
By improving tensile strength and flexibility, RDP effectively reduces shrinkage cracking and improves long-term stability.
Improved Cohesion
The powder increases internal cohesion and minimizes segregation, bleeding, and material loss during application.
Applications of Redispersible Polymer Powder (RDP)
Our Redispersible Polymer Powder (RDP) is widely used in dry mix mortar and construction chemical formulations to improve adhesion, flexibility, water resistance, workability, and durability.
