Momentive SILQUEST A-1891 (γ-mercaptopropyltrimethoxysilane) Silane Coupling Agent enhances adhesion between organic polymers (e.g., rubber, epoxy) and inorganic substrates (e.g., silica, metals) via its mercapto and methoxy groups. It improves mechanical strength, filler dispersion, and crosslinking efficiency in tires, coatings, and composites. Compatible with sulfur-cured systems, it enables rapid curing at ambient temperatures while complying with REACH standards, ideal for low-rolling-resistance tires and rubber hoses
Dual Reactivity - Mercapto bonds with polymers; methoxy links to fillers/metals
Dynamic Performance - Enhances modulus, abrasion resistance, and wet strength retention (>90%)
Process Efficiency - Low viscosity (1.045 g/cm³) for easy filler dispersion
Multi-Matrix Compatibility - Works with EPDM, SBR, and polyurethanes
Sustainability - Halogen-free, reduces VOC emissions in formulation
Tire Manufacturing - Silica reinforcement for low rolling resistance
Rubber Compounding - Seals, hoses with improved wear resistance
Cable Insulation - Enhances dielectric properties in EPDM systems
Anti-Corrosion Coatings - Metal adhesion and chemical resistance
