Momentive A-172NT Silane Coupling Agent

Momentive A-172NT (vinyl tris(2-methoxyethoxy)silane) is a vinyl-functional silane coupling agent that enhances interfacial adhesion between organic polymers (e.g., polyester, EPDM) and inorganic substrates (e.g., glass fibers, fillers). It improves mechanical strength, electrical properties, and wet-condition performance in composites, coatings, and cables. Compatible with radical polymerization systems, it enables covalent bonding while reducing viscosity for easier processing. Ideal for FRP and wire insulation, it complies with REACH standards

Features Of Momentive A-172NT Silane Coupling Agent

  1. Dual Reactivity - Vinyl group bonds with resins; methoxyethoxy links to glass/fillers

  2. Wet-Strength Retention - Enhances mechanical/electrical properties after water exposure

  3. Process Optimization - Lowers viscosity for improved filler dispersion

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

  5. Environmental Safety - Halogen-free, suitable for waterborne systems

Typical Applications Of Momentive A-172NT Silane Coupling Agent

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

  2. Industrial Coatings - Weather-resistant finishes for metal substrates

  3. Adhesive Formulations - Improved bonding in structural adhesives

  4. Rubber Compounding - Mineral-filled EPDM for automotive seals
