Vinabond® H518 is a high-performance redispersible polymer powder (RDP) based on vinyl acetate and ethylene (VAc/E). It is specifically formulated for applications requiring excellent hydrophobicity and water resistance. With a low glass transition temperature (Tg) of -8°C, Vinabond H518 provides outstanding flexibility and elasticity, making it particularly effective in waterproof putty formulations for both interior and exterior surfaces.
Waterproof interior and exterior wall putties
Moisture-resistant smoothing compounds
Pre-mixed cementitious waterproof coatings
Flexible repair and levelling compounds for damp environments
Vinabond® H518 is an ideal redispersible polymer for formulating premium-grade waterproof putties, where both hydrophobicity and flexibility are critical. Its excellent water repellency, low-temperature flexibility, and strong adhesion performance make it a reliable choice for modern construction and finishing systems.
Vinabond® H518 is a high-performance redispersible polymer powder (RDP) based on vinyl acetate–ethylene (VAc/E) copolymer. With an exceptionally low glass transition temperature (Tg) of -8°C, it provides outstanding flexibility and crack resistance. One of the defining characteristics of Vinabond H518 is its superior hydrophobicity, making it particularly suitable for cementitious formulations that require excellent water repellency and long-term durability—such as tile joint fillers used in wet or humid environments.
Cementitious tile joint fillers and grouts
Colored grout for ceramic, porcelain, and natural stone tiles
Water-repellent grouting systems for wet areas
Anti-efflorescence joint fillers for indoor and outdoor use
Vinabond® H518 is the ideal choice for advanced tile grout and joint filler formulations that demand superior waterproofing, flexibility, and surface durability. It ensures long-term aesthetic and functional performance in the most demanding moisture-exposed environments.
