This chemical belongs to the family of trialkoxy silanes, which are characterized by a silicon atom covalently bonded to three alkoxy groups and an organic substituent.
Manufactured and supplied by INNO Specialty Chemicals, a leading chemical company based in China, monophenyl triacetoxysilane is widely used as a crosslinking agent, surface modifier, coupling agent, and adhesion promoter in numerous industries, including construction, automotive, electronics, and coatings.
Properties of Monophenyl Triacetoxysilane
Monophenyl triacetoxysilane is a clear, colorless liquid with a pungent odor. It is soluble in most organic solvents, including alcohols, ethers, and chlorinated hydrocarbons, but insoluble in water. The chemical formula of monophenyl triacetoxysilane is C12H16O6Si, and its molecular weight is 296.34 g/mol.
One of the key properties of monophenyl triacetoxysilane is its high reactivity towards moisture. When exposed to water or atmospheric moisture, it undergoes hydrolysis, forming acetic acid and phenylsilanetriol. This reaction produces a silanol group on the silicon atom, which can then participate in various condensation reactions, leading to the formation of a crosslinked network.
Applications of Monophenyl Triacetoxysilane
Monophenyl triacetoxysilane is a versatile chemical that finds application in various industrial processes. Here are some of the key applications of this compound:
1. Crosslinking agent: Monophenyl triacetoxysilane is used as a crosslinking agent in various organic polymers, such as polyesters, polyurethanes, and epoxies. It reacts with the hydroxyl or carboxyl groups present in the polymer, leading to the formation of a crosslinked network. This improves the mechanical, thermal, and chemical properties of the polymer, making it more durable and resistant to degradation.
2. Surface modifier: Monophenyl triacetoxysilane is used as a surface modifier in various materials, such as glass, ceramics, and metals. It reacts with the surface of the material, forming a thin, hydrophobic layer that improves its water repellency, corrosion resistance, and adhesion properties.
3. Coupling agent: Monophenyl triacetoxysilane is used as a coupling agent in various composite materials, such as fiberglass and carbon fiber composites. It acts as a bridge between the organic polymer and the inorganic filler, improving their compatibility and enhancing the mechanical properties of the composite.
4. Adhesion promoter: Monophenyl triacetoxysilane is used as an adhesion promoter in various adhesive and sealant formulations. It improves the adhesion of the adhesive to the substrate, leading to a stronger and more durable bond.
Safety and Handling of Monophenyl Triacetoxysilane
Monophenyl triacetoxysilane is a hazardous chemical that should be handled with care. It can cause skin and eye irritation, and prolonged exposure can cause respiratory problems. It is also flammable and should be stored in a cool, dry, and well-ventilated area away from sources of heat and ignition.
When handling monophenyl triacetoxysilane, it is essential to wear appropriate personal protective equipment, such as gloves, goggles, and a respirator. It should be stored in a sealed container and kept away from incompatible materials, such as strong acids and bases.
