Momentive Y-9936 (γ-methacryloxypropyltriethoxysilane) is a dual-reactive coupling agent that enhances adhesion between organic polymers (e.g., acrylics, EPDM) and inorganic substrates (e.g., glass fibers, fillers) via methacryloxy and ethoxy groups. It improves mechanical strength, water resistance, and processing efficiency in composites, coatings, and adhesives. Compatible with radical polymerization, it enables covalent bonding while reducing viscosity. Ideal for FRP and cable applications, it complies with REACH standards
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
