Celotech’s Redispersible Polymer Powder (RDP) is a multi-functional polymeric binder engineered to optimize performance in structural repair mortars, thin-layer decorative renders, and tile adhesive systems. This advanced powder modifier delivers critical enhancements:
✔ Enhanced Mechanical Properties – Improves flexural strength (≥8 MPa) and adhesion (≥1.5 MPa) in repair mortars (EN 1504-3 compliant)
✔ Crack Bridging & Shrinkage Compensation – Provides 0.3–0.5mm deformation capacity for thin-layer renders (<5mm thickness)
✔ Tile Adhesive Performance – Achieves EN 12004 C2TE/S1 classifications with >0.5N/mm² wet adhesion
✔ Workability & Durability – Extends open time while ensuring freeze-thaw resistance (50+ cycles, ASTM C666)
Key Applications:
Structural repair mortars (concrete restoration, crack bridging)
Decorative thin-layer renders (polymer-modified finishes, ≤5mm)
High-flexibility tile adhesives (large-format tiles, exterior applications)
Note:Performance values are indicative and derived from typical formulations tested under standard laboratory conditions. Actual results may vary depending on specific formulations and application conditions.
