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

Applications:

Trimethoxysilylpropanethiol 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. Mineral-reinforced articles such as shoe soles, rubber rollers and wheels, white sidewalls, and wire and cable insulation also can be produced with lower silane loadings.

Used to improve properties of mineral filled elastomer, including modulus, tensile and tear strength, heat buildup, abrasion resistance, resilience, compression set and cure time.

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

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

Uses 1. It contains mercapto functional group and has specific efficacy as the metal surface rust inhibitor, and can be applied to the processing of the surface of gold, silver, and copper in order to improve their corrosion resistance, oxidation resistance as well as increase its bonding performance to polymer materials.

2. It is widely applied to filled polymer material, is suitable for thermoset and thermoplastic polymer materials, such as epoxy, eye, phenol sulfonic acid, polyvinyl chloride, polystyrene and polyether sulfone.

3. It has a particularly good efficacy in the rubber industry which can improve its mechanical properties, improve abrasion resistance, and reduce permanent deformation, and is suitable for NR, EPDM, SBR, polysulfide rubber, styrene-butadiene rubber, nitrile rubber, chloroprene rubber, and polyurethane rubber.

4. It is also suitable for a broad range of inorganic fillers such as glass fiber, silica, quartz powder, talc, mica, and fly ash stick.

5. It can be used in various kinds of products such as rubber, plastics, glass fiber, coatings, adhesives, and sealants.

6. It can be used as the treatment agent of glass fiber and a kind of cross-linking agents.

7. It is a kind of silane coupling agent being reactive and cross-linkable. It can be hydrolyzed under acidic or alkaline conditions and is widely used in natural and synthetic rubber as well as being applied to compound materials (such as fiberglass compound material) as a reinforcing agent and cross-linking accelerator, coatings, inks, glues and sealing materials. It also be used as a resin modifier additives and enzyme immobilization agent. It is commonly used in the treatment of inorganic filler such as SiO2 and carbon black and can take effect on polymer such as rubber, silicone rubber as activator, coupling agent, cross-linking agent and reinforcing agent.
