Triethoxyvinylsilane (CAS: 78-08-0), also known as Vinyltriethoxysilane, is a multifunctional organosilicon compound that has garnered significant attention across various industries due to its unique reactivity and application potential. As a leading chemical manufacturer and supplier in China, NINGBO INNO PHARMCHEM CO., LTD. specializes in producing high-quality Triethoxyvinylsilane, facilitating its widespread use in advanced material applications. This article provides an in-depth look at its properties, synthesis, and key industrial applications.

Chemically, Triethoxyvinylsilane is characterized by a vinyl group (-CH=CH2) and three ethoxy groups (-OCH2CH3) attached to a silicon atom (Si). Its molecular formula is C8H18O3Si, with a molecular weight of approximately 190.31 g/mol. It is typically a colorless, transparent liquid with a boiling point around 160-161°C and a flash point of 34°C. The presence of the vinyl group allows it to participate in addition polymerization and other radical-initiated reactions, while the ethoxy groups are hydrolyzable, enabling it to react with hydroxyl groups on inorganic surfaces and form stable siloxane bonds. These dual functionalities make it an exceptional silane coupling agent and adhesion promoter. Buyers seeking to purchase Triethoxyvinylsilane often do so for these specific reactive properties.

The synthesis of Triethoxyvinylsilane typically involves the hydrosilylation of acetylene with triethoxysilane. This process, carried out under controlled conditions and often in the presence of a catalyst, yields the desired vinyl-functional silane. Manufacturers like NINGBO INNO PHARMCHEM CO., LTD. ensure that their production processes adhere to strict quality control measures to guarantee high purity and consistency, which are critical for its performance in demanding applications. The availability of Triethoxyvinylsilane from reliable manufacturers in China is a key factor for global supply chains.

The primary applications of Triethoxyvinylsilane span across multiple sectors. In the plastics and rubber industries, it serves as a coupling agent to improve the adhesion between fillers (like silica or glass fibers) and polymer matrices, enhancing mechanical properties such as tensile strength and impact resistance. It is also used as a crosslinking agent in moisture-curable polymers, providing improved thermal and mechanical stability. In coatings, adhesives, and sealants, Triethoxyvinylsilane enhances adhesion to various substrates, improves durability, and increases resistance to water and chemicals. Furthermore, it finds use in the synthesis of specialty polymers and for surface modification applications. The versatility of Triethoxyvinylsilane applications makes it a cornerstone chemical for material innovation.
