Celotech’s Redispersible Polymer Powder (RDP) is a versatile polymeric modifier engineered to enhance the performance of concrete repair mortars and flexible skim coats. This advanced additive delivers critical improvements in:
✔ Adhesion & Bond Strength – Achieves ≥1.5 MPa tensile adhesion (EN 1504-3 compliant for repair mortars)
✔ Flexibility & Crack Resistance – Provides ≥0.3 mm deformation capacity (EN 14891 for waterproofing mortars)
✔ Workability & Cohesion – Enhances application smoothness and anti-sag properties in thin-layer skim coats
Key Applications:
Structural Concrete Repair Mortars (EN 1504-3, ASTM C928 compliant)
Flexible Skim Coats (reduced shrinkage cracking, improved impact resistance)
Note: Performance data referenced above is based on standard testing conditions and formulation examples. Actual performance may vary depending on raw materials and formulation design.
