Momentive SILQUEST G-170 Silane Coupling Agent

Momentive SILQUEST G-170 (vinyltriethoxysilane) is a proprietary coupling agent that optimizes interfacial bonding between glass fibers and resins (polyester, epoxy). It enhances mechanical strength, wet electrical properties, and filler dispersion in composites while reducing VOC emissions during cable/rubber production. Ideal for FRP and crosslinked polyethylene applications, it complies with REACH standards, offering eco-efficient solutions for automotive and construction materials

Features Of Momentive SILQUEST G-170 Silane Coupling Agent

  1. Interfacial Reinforcement - Vinyl groups bond with resins; ethoxy links to fibers/fillers, improving wet strength retention (>90%)

  2. Process Sustainability - Reduces volatile alcohol byproducts (e.g., methyl cellosolve) in wire/cable manufacturing

  3. Multi-Matrix Compatibility - Effective in EPDM rubber, HFFR-filled compounds, and polyester resins

  4. Eco-Design - Halogen-free, meets ZDHC MRSL and GOTS standards for industrial safety

Typical Applications Of Momentive SILQUEST G-170 Silane Coupling Agent

  1. FRP Composites - Glass fiber sizing for improved moisture resistance in automotive parts

  2. Wire & Cable - Crosslinked polyethylene insulation with enhanced dielectric properties

  3. Rubber Compounding - Silica-filled tires for reduced rolling resistance

  4. HFFR Materials - Pretreatment for magnesium/aluminum hydroxide flame retardants
