Celotech’s Redispersible Polymer Powder (RDP) is a white, free-flowing solid powder designed to redisperse in water and form a stable latex during mixing. It enhances key performance attributes in waterproofing mortars, flexible tile adhesives, and crack-bridging formulations, offering:
✔ Excellent Water Repellency – Helps reduce water absorption to below 5%, while maintaining breathability
✔ Strong Adhesion – Supports tensile bond strength levels often required in demanding applications (e.g., C2TE/S1-class adhesives under EN 12004)
✔ Crack Bridging Capability – Offers ≥0.5 mm deformation flexibility for stress absorption in dynamic systems
✔ Long-Term Durability – Improves freeze-thaw stability (tested to >50 cycles per ASTM C666) and overall weather resistance
Recommended Uses:
Waterproofing mortars and cementitious membranes
Flexible tile adhesives for large-format or exterior tiles
Crack-bridging and elastomeric mortar systems
Note: Performance values referenced are based on commonly used international test methods (e.g., EN 12004, EN 14891, ASTM C666), for comparison purposes only. Users are advised to conduct in-house validation.

Vinabond® H517 is a hydrophobic redispersible polymer powder (RDP) based on vinyl acetate-ethylene (VAc/E) copolymer, specially developed for cement-based waterproofing systems. Featuring a neutral glass transition temperature (Tg), it provides a well-balanced profile between flexibility and strength. In addition, Vinabond H517 exhibits enhanced hydrophobicity, offering superior water resistance in wet or high-humidity environments.
Cementitious waterproofing coatings
Flexible waterproof mortars for basements, wet rooms, terraces, and balconies
Crack-bridging layers for concrete protection
Waterproof plasters in indoor and outdoor environments
Vinabond® H517 combines a neutral Tg performance with relatively high hydrophobicity, making it a reliable and effective RDP choice for cement-based waterproofing mortars. It enhances water resistance, durability, flexibility, and adhesion, helping formulators meet the high demands of modern construction applications where moisture protection is essential.
