Product Introduction:
Triethoxyoctylsilane (C14H32O3Si) is an organosilicon compound with the chemical formula C14H32O3Si and belongs to the class of organosilicon substances, with various applications including surface treatment, improving material properties, surface modifier use and surface modification. As it’s typically coloredless and transparent liquid at room temperature and has limited volatility and flammability characteristics – as well as typical organosilicon properties such as heat resistance and corrosion resistance – its primary use lies within surface treatments, material properties enhancement or surface modifications or surface modifications.
Triethoxyoctylsilane exhibits excellent lipophilicity and hydrophilicity properties, featuring hydrolyzable ethoxy groups within its structure that hydrolyze when exposed to water, producing alcohols and silanol groups which react chemically with the hydroxyl groups on surfaces to form strong covalent bonds, providing effective modification and adhesion properties on inorganic materials, glass, metals, polymers and other surfaces. Due to these features, this compound has become widely used in surface treatment of inorganic materials, glass, metals metals polymers etc.
Triethoxyoctylsilane can be found in applications ranging from coatings and sealants, through adhesives and fiber-reinforced composites, and sealants to fiber-reinforced composites. As a component in coatings it enhances adhesion, weather resistance and water resistance of coatings while in adhesives it enhances adhesion particularly on metal or glass surfaces under high humidity environments. Furthermore, triethoxyoctylsilane has found widespread application in high performance composite materials production as well as surface treatments of electronic devices.
Triethoxyoctylsilane plays an essential role in the preparation of nanomaterials and reinforced materials. Through chemical bonding, organic molecules can connect with inorganic materials (such as silica nanoparticles) via organic molecules; this increases material performance such as dispersibility, mechanical strength and thermal stability thereby contributing to research into nanotechnology and composite materials. It thus plays an integral part in research of nanotechnology and composites.

Triethoxyoctylsilane is a widely used organosilicon compound. It is often used to improve the compatibility between materials and improve performance, and plays an important role in many fields. It is a long-chain alkyl silane coupling agent that enhances the bonding force between organic and inorganic materials by reacting the ethoxy groups in its molecules with the hydroxyl groups on the surface of inorganic materials.
First, triethoxyoctylsilane plays an important role in surface modification and enhancing material compatibility. In the manufacturing of composite materials, it forms silicon-oxygen covalent bonds through surface reaction with inorganic materials (such as glass fiber, silica, ceramics, etc.), thereby strengthening the relationship between the organic matrix (such as plastics, rubber, oils, adhesives, etc.) and Adhesion between inorganic materials.
This results in composite materials with better mechanical properties, impact resistance and durability. Especially in the application of fiber-reinforced plastics, Triethoxyoctylsilane significantly improves the bonding force between resin and fiber.
Triethoxyoctylsilane is also widely used in coating and adhesive formulations as an additive to enhance adhesion and durability. In the field of coatings, it can improve the adhesion between the coating and various substrates (such as metal, glass, ceramics, plastics, etc.), and improve the corrosion resistance and water resistance of the coating. This makes it widely used in automobiles, architectural coatings and other fields. At the same time, in adhesives, it enhances the bonding force between adhesives and inorganic materials, especially in humid environments, improving the performance of adhesives.
In the protection of optical materials, Triethoxyoctylsilane plays a significant role as an anti-fogging agent. It can form a transparent protective film on the glass surface to prevent water vapor from condensing and maintain clear vision. It is often used for anti-fog treatment on car windshields, optical instrument lenses, display screens and other surfaces to improve the clarity of vision. In addition, it can also maintain the transparency of the glass surface in the anti-fog treatment of architectural glass, especially in humid environments.
Triethoxyoctylsilane also has important applications in the field of cultural relics protection. It can effectively prevent damage to cultural relics caused by natural factors such as acid corrosion, freeze-thaw and weathering, especially the protection of outdoor cultural relics. By reacting with the surface of cultural relics, a protective film is formed to prevent the penetration of moisture and pollutants and extend the life of cultural relics. Stone sculptures, ceramics, wooden cultural relics, etc. can better resist the erosion of the external environment after being treated with Triethoxyoctylsilane.
In the textile industry, Triethoxyoctylsilane is used as a fabric finishing agent to give fabrics better feel, smoothness and hydrophobicity. It can make cotton, linen, wool and blended fabrics feel smoother and effectively improve the waterproof properties of the fabrics. This makes it widely used in outdoor sportswear, waterproof fabrics and home textiles. At the same time, it can also enhance the durability of the fabric, reduce the adhesion of stains, and improve the anti-fouling performance of the fabric.
In the construction industry, Triethoxyoctylsilane is widely used for waterproofing and anti-corrosion treatments. It can penetrate into the surface of concrete, masonry, stone and other building materials to form a waterproof protective film to prevent moisture penetration and reduce structural damage caused by moisture. Especially in the treatment of building exterior walls, it can improve the water resistance and weather resistance of wall materials, thereby extending the service life of the building.
In addition, Triethoxyoctylsilane functions as a release agent in the manufacture of rubber and plastics. It can reduce the adhesion between the mold and the molded product, reduce the wear and cleaning frequency of the mold during the production process. This not only improves production efficiency, but also extends the service life of the mold, especially in the molding process of rubber and engineering plastics.
Wide range of applications: Due to its unique molecular structure, Triethoxyoctylsilane is used in aerospace, electronics, textiles, light industry, construction, medical, food and other fields, showing its versatility.
Improved compatibility: As a long-chain alkyl silane coupling agent, Triethoxyoctylsilane can effectively improve the compatibility between inorganic and organic materials and enhance the mechanical properties of products.
Excellent waterproof performance: In the field of construction, Triethoxyoctylsilane can be used to form a hydrophobic layer, effectively preventing water seepage, sun exposure and acid and alkali erosion, and extending the service life of buildings.
Environmental protection: Compared with some other silane coupling agents, Triethoxyoctylsilane has a slower hydrolysis rate and better stability in aqueous systems. The by-product of the hydrolysis reaction is ethanol, which is relatively environmentally friendly.
Wetting and thickening effects: In the surface modification of cosmetic powders, Triethoxyoctylsilane has good wetting properties and a certain thickening effect, which helps to improve the dispersion and uniformity of powders.
Stable physical and chemical properties: Even at low pH values, pigments treated with triethoxyoctylsilane remain stable, with no residual methanol and no risk of releasing hydrogen.
Good permeability: The unique small molecule structure of triethoxyoctylsilane has excellent permeability and can penetrate into the base surface to form a long-lasting hydrophobic three-dimensional silicone network structure.
