Silane Coupling Agent
Vinyltrimethoxysilane (VTMO) silane coupling agent used to treat mineral fillers and glass fibers to improve bonding with polyolefin and polyester matrices. It is also used as a crosslinking agent in moisture-crosslinkable polyethylene and as a surface treatment agent in silica-filled rubber systems. Provides excellent improvement in composite mechanical properties and moisture resistance.
