3-Mercaptopropyltrimethoxysilane (MPTS) is a functional silane that has a hydrolysable methoxy group and a reactive mercapto group. It can act as a silane coupling agent that can promote the adhesion between organic materials and inorganic substrates, such as metals, glass, silica, and kaolin. It can also be used as a surface modifier, a crosslinker, a resin additive, and a finishing agent.
MPTS is mainly used in tires and silicone rubbers as a surface modifier and an adhesion promoter. It can improve the mechanical and electrical properties of these materials by forming strong bonds with the fillers and the rubber matrix. MPTS can also enhance the resistance to heat, moisture, and corrosion.
MPTS is also used in coatings, adhesives, sealants, and paints as an adhesion promoter and a filler/pigment modifier. It can improve the dispersion, compatibility, and stability of the inorganic components in the organic matrix. MPTS can also increase the durability, hardness, gloss, and water repellency of the coatings.
MPTS is also used in biomedical applications as a surface modifier and an adhesion promoter for metal implants, such as titanium, stainless steel, and cobalt-chromium alloys. MPTS can form a self-assembled monolayer on the metal surface that can improve the biocompatibility, osteointegration, and antibacterial properties of the implants. MPTS can also be used to immobilize biomolecules, such as proteins, enzymes, antibodies, and DNA, on the metal surface for biosensing and bioanalysis.
MPTS is widely used in China as a functional silane for various industries. According to a report by Shandong Pengrun New Materials Co., Ltd., a leading manufacturer and supplier of silanes in China, MPTS accounted for 15% of the total silane consumption in China in 2020. The demand for MPTS is expected to grow steadily in the coming years due to its versatile applications and benefits.

MPTS improves the adhesion of materials by forming strong chemical bonds between the mercapto group and the organic materials, and between the methoxy group and the inorganic substrates. The mercapto group can react with various functional groups, such as hydroxyl, carboxyl, epoxy, and vinyl, to form covalent bonds. The methoxy group can hydrolyze in the presence of water and form silanol groups, which can further condense with the hydroxyl groups on the inorganic surfaces to form siloxane bonds. These bonds can enhance the interfacial compatibility and reduce the interfacial stress between the organic and inorganic phases. MPTS can also act as a crosslinker or a resin additive to improve the cohesion and performance of the organic materials.
Some other silane coupling agents are:
– Vinyltrimethoxysilane (VTMO), which can be used to modify polyethylene, polypropylene, and other polymers to improve their adhesion to metals, glass, and ceramics.
– Aminopropyltriethoxysilane (APTES), which can be used to modify epoxy, polyurethane, acrylic, and other resins to improve their adhesion to metals, glass, and ceramics. It can also be used to functionalize silica nanoparticles, carbon nanotubes, and other nanomaterials for biomedical and nanotechnology applications.
– Glycidoxypropyltrimethoxysilane (GPTMS), which can be used to modify epoxy, polyester, and other resins to improve their adhesion to metals, glass, and ceramics. It can also be used to immobilize biomolecules, such as proteins, enzymes, antibodies, and DNA, on metal surfaces for biosensing and bioanalysis.
– Mercaptosilanes, such as 3-mercaptopropyltrimethoxysilane (MPTS), which can be used to modify rubber, silicone, and other elastomers to improve their adhesion to metals, glass, and ceramics. They can also be used to enhance the mechanical and electrical properties of these materials by forming strong bonds with the fillers and the rubber matrix.
