FD800-Epoxy Structural Adhesive is a high-performance, two-component system designed for vertical and horizontal splicing of precast concrete segments in onshore hybrid wind turbine towers. It offers strong, weather-resistant bonding with excellent thixotropy for vertical application and high compressive and shear strength for post-tensioned assemblies.
🔩 Engineered for Wind Turbine Tower Segments
💪 High Compressive and Shear Strength
🧱 Strong Adhesion to Concrete and Steel
💧 Waterproof & Anti-Corrosion
❄️ Wide Temperature Range: -25°C to +50°C
🧴 Non-Sag Paste for Vertical & Overhead Application
Product Introduction
Epoxy Structural Adhesive is a high-strength, weather-resistant bonding agent designed for splicing precast concrete segments in hybrid wind turbine towers.
