Momentive SILQUEST A-174NT115 (γ-methacryloxypropyltrimethoxysilane) enhances adhesion between organic polymers (e.g., acrylics, EPDM) and inorganic substrates (e.g., glass, metals) via radical-curable methacryloxy and methoxy groups. It improves mechanical strength, wet adhesion (>90% retention), and filler dispersion in composites, coatings, and adhesives. Compatible with free-radical curing systems, it reduces viscosity (1.045 g/cm³) and complies with REACH standards for industrial applications
Dual Reactivity - Methacryloxy bonds with resins; methoxy links to fillers/metals
Dynamic Performance - Enhances wet/dry adhesion and abrasion resistance
Process Efficiency - Lowers viscosity for easier processing
Multi-Matrix Compatibility - Works with polyesters, epoxies, and elastomers
Sustainability - Halogen-free, low VOC emissions
FRP Reinforcement - Glass fiber sizing for high-strength composites
Wire & Cable - Mineral-filled EPDM insulation with improved dielectric properties
Hybrid Coatings - UV-curable systems for metal/plastic substrates
Rubber Compounding - Reinforced seals and hoses for automotive
