Momentive E-FREE189 is a mercapto-functional silane coupling agent that enhances filler dispersion and polymer-filler bonding in rubber, coatings, and composites. It reduces rolling resistance in tires by >20% while maintaining wet grip, and lowers VOC emissions by 97% compared to traditional silanes Compatible with silica-filled systems, it improves mechanical strength, aging resistance, and processing efficiency, meeting REACH standards for eco-friendly industrial applications
Emission Reduction - Virtually eliminates ethanol emissions (>97%) during manufacturing
Performance Efficiency - Achieves target properties at reduced dosage (1-3 wt%)
Dynamic Properties - Enhances modulus (up to 30%) and abrasion resistance in rubber
Process Optimization - Lowers viscosity and prevents premature scorching
Multi-Matrix Compatibility - Works with EPDM, SSBR, polyesters, and epoxies
Green Tires - Silica-reinforced treads for fuel-efficient vehicles
Industrial Rubber - Seals, hoses, and belts with extended service life
Anti-Corrosion Coatings - Improved filler dispersion for metal protection
Structural Composites - Glass fiber/polyester reinforcement for FRP
