Momentive WETLINK78 is an epoxy-functional silane coupling agent optimized for waterborne adhesives and sealants. It enhances wet adhesion, mechanical strength, and storage stability in one-component systems through covalent bonding between organic polymers and inorganic substrates. Ideal for automotive, furniture, and construction applications, it offers non-yellowing performance, rapid curing at ambient temperatures, and compliance with environmental regulations
Dual-Functionality - Methacryloxy bonds with resins; ethoxy links to glass/fillers
Wet-Strength Retention - Maintains >90% bond strength after water immersion
Process Optimization - Low viscosity (0.985 g/cm³) for easy filler dispersion
Multi-Matrix Compatibility - Works with polyesters, epoxies, and elastomers
Sustainability - Halogen-free, suitable for solvent/waterborne systems
FRP Reinforcement - Glass fiber treatment for high-strength composites
Wire & Cable - Mineral-filled EPDM insulation with enhanced dielectric properties
Hybrid Coatings - UV-curable systems with improved metal/plastic adhesion
Rubber Compounding - Reinforced elastomers for automotive seals
Adhesive Formulations - Structural bonding with moisture resistance
