- Functions:Crosslinking Agent, Coupling Agent, Adhesion Promoter
- Chemical Family:Silanes
- Compatible Polymers & Resins:Synthetic Rubbers
Silquest™ A-189 silane chemically bonds reinforcing minerals such as silica, clay, mica and talc to the polymer matrix. This silane is especially useful in sulfur-cured and metal oxide-cured elastomers. It can be used as a pretreatment on minerals or added at the time of compounding.Improvement in mineral-filled elastomer properties, including modulus, tensile and tear strength, heat buildup, abrasion resistance, resilience, compression set and cure time may be achieved with Silquest™ A-189 silane (gamma-mercaptopropyltrimethoxysilane).
