RDP Powder Details
Product Performance & Features
  • Redispersibility RDP/VAE can redisperse in water to form a stable polymer emulsion, regaining the properties of the original latex.
  • Adhesion Improvement Provides strong bonding between substrates (cement, gypsum, or plaster) and surfaces like concrete, wood, or tiles.
  • Flexibility & Elasticity Enhances deformation resistance, reducing cracking under thermal or mechanical stress.
  • Water Retention Helps mortars and adhesives retain moisture, improving workability and curing.
  • Abrasion & Impact Resistance Increases surface strength and durability, making mortars more resistant to wear and external forces.
  • Workability Improves smoothness, spreadability, and open time of cement-based mixtures.
  • Weather & Freeze–Thaw Resistance Provides excellent resistance against environmental changes, improving outdoor durability.
  • Alkali Resistance Maintains stability in high-alkaline cementitious environments, ensuring long-term performance.
