Product Description:
Improvement in mineral-filled elastomer properties, including modulus, tensile and tear strength, heat buildup, abrasion resistance, resilience, compression set and cure time are achieved with Silquest® A-189 silane. 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.
Silquest silanes are extremely versatile products that can react with a wide variety of organic and inorganic materials. Their unique ability as coupling agents, crosslinking agents, and
surface modifiers has been proven in an ever-increasing number of applications, ranging from adhesives to coatings to foundry binder resins.
Coatings
moisture-initiated crosslinking of resins, improved adhesion, chemical and corrosion resistance, weatherability, pigment dispersion, scrub resistance and binders
Printing inks
improved adhesion, release and wetting
