Features Of Momentive Silquest A-172NT Vinyl tris(2-methoxyethoxy)silane

  1. Reactive vinyl functionality enables covalent bonding with unsaturated polymers (e.g., SBR, BR, EPDM) during compounding and curing.

  2. Hydrolytically stable alkoxy groups provide extended shelf life and reduced moisture sensitivity compared to triethoxysilanes.

  3. Low volatility and favorable handling characteristics due to high molecular weight and low vapor pressure.

  4. Enhances filler dispersion and polymer–filler interaction in silica-reinforced rubber compounds.

  5. Improves mechanical properties including tensile strength, abrasion resistance, and dynamic performance in tire treads.

Typical Applications Of Momentive Silquest A-172NT Vinyl tris(2-methoxyethoxy)silane

  1. Tire tread compounds for passenger and truck radial tires.

  2. Silica-reinforced elastomeric seals and gaskets.

  3. High-performance rubber hoses and belts requiring low rolling resistance.

  4. Dynamic rubber components in automotive suspension systems.
