Momentive Y-9936 Silane Coupling Agent

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

Features Of Momentive Y-9936 Silane Coupling Agent

  1. Dual-Functionality - Methacryloxy bonds with resins; ethoxy links to glass/fillers

  2. Wet-Strength Retention - Maintains >90% bond strength after water immersion

  3. Process Optimization - Low viscosity (0.985 g/cm³) for easy filler dispersion

  4. Multi-Matrix Compatibility - Works with polyesters, epoxies, and elastomers

  5. Sustainability - Halogen-free, suitable for solvent/waterborne systems

Typical Applications Of Momentive Y-9936 Silane Coupling Agent

  1. FRP Reinforcement - Glass fiber treatment for high-strength composites

  2. Wire & Cable - Mineral-filled EPDM insulation with enhanced dielectric properties

  3. Hybrid Coatings - UV-curable systems with improved metal/plastic adhesion

  4. Rubber Compounding - Reinforced elastomers for automotive seals

  5. Adhesive Formulations - Structural bonding with moisture resistance
