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
Dual Reactivity - Vinyl group bonds with resins; methoxyethoxy links to glass/fillers
Wet-Strength Retention - Enhances mechanical/electrical properties after water exposure
Process Optimization - Lowers viscosity for improved filler dispersion
Multi-Matrix Compatibility - Works with polyesters, epoxies, and elastomers
Environmental Safety - Halogen-free, suitable for waterborne systems
FRP Reinforcement - Glass fiber treatment for high-strength composites
Industrial Coatings - Weather-resistant finishes for metal substrates
Adhesive Formulations - Improved bonding in structural adhesives
Rubber Compounding - Mineral-filled EPDM for automotive seals
