Vinyltrimethoxysilane (VTMS), identified by CAS Number 2768-02-7, is a fundamental organosilicon compound that serves as a critical silane coupling agent. Its unique molecular structure, featuring a reactive vinyl group and hydrolyzable methoxy groups, allows it to bridge the gap between organic and inorganic materials, enhancing adhesion, compatibility, and overall material performance across numerous industries. As a premier manufacturer and supplier, we are dedicated to providing high-purity VTMS to facilitate innovation and production efficiency for our clients.

The chemical structure of VTMS, CH2=CHSi(OCH3)3, is central to its functionality. The three methoxy groups are susceptible to hydrolysis in the presence of moisture, forming reactive silanol (Si-OH) groups. These silanol groups can then condense with each other to form siloxane (Si-O-Si) bonds, or react with hydroxyl groups present on the surface of inorganic materials like glass, metals, or mineral fillers. This process anchors the silane to the inorganic substrate. Concurrently, the vinyl group is highly reactive and can participate in free-radical polymerization or addition reactions, readily bonding with organic polymer matrices such as polyolefins, polyesters, or acrylics. This bifunctional nature is what makes VTMS an exceptional coupling agent.

The properties of VTMS are crucial for its successful application. It is typically a colorless, transparent liquid with a relatively low viscosity. While it is reactive with moisture, it remains stable when stored under anhydrous conditions. Its boiling point is around 123°C, and it has a flash point of approximately 25°C, classifying it as a flammable liquid that requires appropriate handling and storage procedures. We, as a leading supplier in China, ensure our VTMS adheres to stringent quality specifications for purity and consistency, vital for predictable performance in your applications.

The applications of VTMS are extensive and impactful. It is widely used as an adhesion promoter in coatings, adhesives, and sealants, improving their bond strength and durability on various substrates. In the plastics and rubber industries, VTMS enhances the mechanical properties of filled composites by improving filler dispersion and interfacial adhesion. It also serves as a crosslinking agent for polymers like polyethylene, imparting improved thermal and chemical resistance. For manufacturers looking to buy VTMS, understanding these applications allows for targeted formulation improvements. Our company is committed to providing a reliable supply of VTMS to support these diverse industrial needs.
