Celotech’s Redispersible Polymer Powder (RDP) is a versatile polymeric modifier engineered to enhance key performance characteristics in External Thermal Insulation Composite Systems (ETICS), skim coats, tile adhesives, and cementitious grouts. This advanced powder binder delivers:
✔ Superior Adhesion Strength – Enhances bond performance in ETICS base coats (EN 13499) and tile adhesives (EN 12004 C1/C2/S1/S2 compliant)
✔ Crack Resistance & Flexibility – Improves tensile strength and deformation capacity (>0.5mm) for long-term durability
✔ Water Resistance & Workability – Reduces water absorption (<5% in grouts per EN 13888 CG2) while optimizing open time and application smoothness (depending on formulation and dosage)
✔ Impact & Weather Resistance – Critical for ETICS renders and exterior skim coats exposed to thermal cycling
Key Applications:
ETICS base & finishing coats (improved impact & weather resistance)
High-performance skim coats (reduced shrinkage cracking)
Flexible tile adhesives (S1/S2 classifications for large-format tiles)
Polymer-modified grouts (enhanced waterproofing & abrasion resistance)
Compliance: Compatible with systems designed to meet EN 13499 (ETICS), EN 12004 (tile adhesives), and EN 13888 (cementitious grouts), when properly formulated.
Note: Performance data provided above are based on internal testing with typical formulations under controlled conditions. Final performance depends on system formulation, application techniques, and job-site variables.
Disclaimer: Mentions of international standards such as EN 13499, EN 12004, and EN 13888 are for reference only. Celotech’s RDP products are compatible with systems designed to meet these standards, but do not constitute certification or compliance unless tested and confirmed by the formulator or system integrator. Users are responsible for conducting their own validation testing to ensure fitness for use.
