Overview

Redispersible Polymer Powder (RDP) is a spray‑dried polymer powder that re‑disperses in water to form a polymer binder. In dry‑mix mortars and cementitious systems, it improves adhesion, flexibility, abrasion resistance, and workability where compatible with the formulation.

Typical applications

  • Tile adhesives (C1/C2 classes depending on formulation)
  • EIFS/base coats and repair mortars
  • Self‑leveling underlayments and smoothing compounds
  • Grouts and skim coats

What to specify (procurement checklist)

  • Polymer type (commonly VAE or acrylic-based, depending on performance and cost targets)
  • Minimum film‑forming temperature / Tg (impacts flexibility and low‑temperature performance)
  • Ash / mineral content (affects mortar density and cost-in-use)
  • Bulk density and flow (handling in dry blending)
  • Redispersibility (stability and performance in water)
  • Recommended dosage range for your application class

Handling & storage

  • Store sealed, dry, and cool. Protect from moisture uptake.
  • Use FIFO. If clumping is observed, investigate storage humidity and bag integrity.
  • For export, specify pallet wrap and moisture barrier where needed.

Note: RDP selection is formulation-dependent. Sharing your base formulation and target standard (e.g., tile adhesive class) helps us recommend a cost-effective grade.
