Momentive SILQUEST A-174NT115 Silane Coupling Agent

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

Features Of Momentive SILQUEST A-174NT115 Silane Coupling Agent

  1. Dual Reactivity - Methacryloxy bonds with resins; methoxy links to fillers/metals

  2. Dynamic Performance - Enhances wet/dry adhesion and abrasion resistance

  3. Process Efficiency - Lowers viscosity for easier processing

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

  5. Sustainability - Halogen-free, low VOC emissions

Typical Applications Of Momentive SILQUEST A-174NT115 Silane Coupling Agent

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

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

  3. Hybrid Coatings - UV-curable systems for metal/plastic substrates

  4. Rubber Compounding - Reinforced seals and hoses for automotive
