Monophenyltriethoxysilane, also known as triethoxy(phenyl)silane or phenyltriethoxysilane, is a colorless to light yellow liquid with a density of 1.03 g/cm3 and a boiling point of 240 °C. It is mainly used as a crosslinking agent, coupling agent, and surface modifier in various industries, such as the production of silicone rubber, adhesives, coatings, and plastics. Ningbo Inno Pharmchem Co., Ltd. is a reliable supplier and manufacturer of high-quality monophenyltriethoxysilane, offering competitive prices and excellent customer service.

Chemical Properties

Monophenyltriethoxysilane has the chemical formula C10H16O3Si, with a molecular weight of 212.31 g/mol. It is a silane coupling agent, meaning it has both organic and inorganic functional groups that can bond to both organic and inorganic materials. The triethoxysilane group (-Si(OC2H5)3) can react with the hydroxyl (-OH) groups on the surface of various substrates, such as glass, metal, and mineral fillers, forming a covalent bond and improving the adhesion between the substrate and the organic material. The phenyl group (-C6H5) can provide hydrophobicity and improve the thermal and mechanical properties of the material.

Monophenyltriethoxysilane is compatible with various organic solvents, such as ethanol, acetone, and benzene, but it is hydrolytically unstable in the presence of water or moisture. It can react with water to form silanol (-Si-OH) groups, which can further condense to form siloxane (-Si-O-Si-) bonds and release ethanol as a byproduct. Therefore, monophenyltriethoxysilane should be stored in a dry and cool place, and the container should be tightly closed to prevent moisture absorption.

Market Prospect

Monophenyltriethoxysilane has a wide range of applications in various industries, such as:

- Silicone rubber: Monophenyltriethoxysilane can act as a crosslinking agent for silicone rubber, improving its mechanical properties, such as tensile strength, tear resistance, and elongation at break. It can also improve the heat resistance and aging resistance of silicone rubber, making it suitable for high-temperature and harsh environments, such as automotive and aerospace applications.

- Adhesives and sealants: Monophenyltriethoxysilane can act as a coupling agent for adhesive and sealant formulations, improving their adhesion to various substrates, such as metals, plastics, and glass. It can also improve the water resistance and durability of the adhesive and sealant, making it suitable for outdoor and marine applications.

- Coatings: Monophenyltriethoxysilane can act as a surface modifier for coatings, improving their scratch resistance, hardness, and adhesion to various substrates. It can also provide hydrophobicity and anti-corrosion properties to the coating, making it suitable for architectural, automotive, and industrial coatings.

- Plastics: Monophenyltriethoxysilane can act as a coupling agent for plastic formulations, improving their mechanical and thermal properties, such as impact strength, tensile modulus, and heat resistance. It can also improve the surface finish and adhesion of the plastic, making it suitable for electronic, medical, and consumer goods applications.

The global market for monophenyltriethoxysilane is expected to grow at a CAGR of 4.5% from 2021 to 2026, driven by the increasing demand for high-performance materials in various industries.
