Trimethoxysilylpropanethiol Usage And Synthesis

Silane coupling agent KH-590	Silane coupling agent KH-590 is the earliest widely applied coupling agent and so far has a history of more than 40 years. One end of its structure contains active groups such as amino group and vinyl group which are capable of having reaction with various kinds of synthetic resin molecules including epoxy, phenolic, and polyester. The other end includes either alkoxy group (e.g. methoxy, ethoxy, etc.) or a chlorine atom which are connected to silicon. These groups, in the presence of an aqueous solution or moisture in the air, can be hydrolyzed to be able to react with glass, minerals, and the surface hydroxyl group of inorganic filler to generate reactive silanols. Accordingly, the silane coupling agent is commonly used in the silicate-filled epoxy, phenolic and polyester resin systems. In addition, it can also be used for the production of the glass steel in order to improve their mechanical strength and resistance to humid environments. The organic groups of the silane coupling agent have selectivity on the reaction of the synthetic resin. In general, these organic groups don’t have enough reactivity with synthetic resin such as polyethylene, polypropylene and polystyrene, and thus having poor coupling effects. In recent years, it has been developed of new variety of silane coupling agent with better coupling effect with polyolefin. However, limited by the cost and other performance, its application is still not wide enough. Silane coupling agent is also known as silane treatment agent or primer. Its general chemical formula is Y (CH2) nSiX3 which contains organosilicon monomers with two or more different reactive groups in the molecule. It can have chemical coupling reaction with both inorganic and organic materials to increase the adhesion between the two kinds of materials. The n in the general chemical formula is an integer of 0 to 3; X is a hydrolyzable group such as chloro, methoxy, ethoxy, acetoxy, etc., It is easily to be hydrolyzed into silanols and can have reaction with inorganic materials and further bind to them; the Y is organic functional groups, such as vinyl, amino, epoxy, methacryloxy group, and mercapto group, etc., it can react with organic materials and bind to them. The performance of typical silane coupling agent is as follows: can be used for the treatment of glass fiber and inorganic filler surface; can be used as sealants, adhesives and coatings thickener; also can be applied to ensure the immobilize enzyme be attached to the glass substrate surface, sand prevention for oil well drilling, making masonry surfaces be water-repellent, endowing the coating of fluorescent lamp with a high surface resistance, and also improving the hygroscopic effect of the surface of the organic glass in the liquid chromatography. It is prepared from the adduct reaction between silicon chloroform and active group containing olefin in the catalysis of platinum and further alcoholysis. The above information is edited by the chemicalbook of Dai Xiongfeng.
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.
