SiSiB® PC2320 is a clear, colorless to light yellow liquid with a slightly mercaptan odor. It is a bifunctional organosilane possessing a reactive organic mercapto and a hydrolyzable inorganic methoxysilyl group. It can be used as coupling agent to improve the adhesion of sulfur cured elastomers (polysulfide, polyurethane sealants) to inorganic fillers (such as silica, clay, glass, mica and talc etc.), fiberglass and surfaces; to improve properties of mineral filled elastomer, including modulus, tensile and tear strength, heat buildup, abrasion resistance, resilience, compression set and cure time; as a pretreatment on minerals or added at the time of compounding; or to improve low-rolling resistance in silica-reinforced tire tread compounds.
SiSiB Silicones has more than 20 years’ experience in manufacturing various silicone materials. They have established six factories in China to manufacture organofunctional silanes (silane coupling agents, silane crosslinkers, silane blocking agents), silicone fluids (straight, modified), silicone rubbers (Gum, HTV, RTV and LSR), silicone resins and fumed silica.
SiSiB® silanes are widely used in adhesives and sealants to improve environmental resistance, increase adhesion and other mechanical properties and can be used to improve the adhesion of many coatings (urethanes, epoxies, phenolics and others) to glass and metal surfaces for the paint and coating industry.
