Product Detail

Brand name: GX-590

Formula:C6H16O3SSi

Purity: 97%min

Physical Properties

GX-590 is a bifunctional organosilane possessing a reactive organic mercapto and a hydrolyzable inorganic methoxysilyl group. A clear, colorless to light yellow liquid with a slightly mercaptan odor. It is soluble in alcohols, ketones and aliphatic or aromatic hydrocarbons.

Application:

1. GX-590 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.

2. GX-590 is used to improve properties of mineral filled elastomer, including modulus, tensile and tear strength, heat buildup, abrasion resistance, resilience, compression set and cure time.

3. Used as a pretreatment on minerals or added at the time of compounding.

4. Used to improve low-rolling resistance in silica-reinforced tire tread compounds.
