Properties of Allyltriethoxysilane

Allyltriethoxysilane has a chemical formula of C9H20O3Si, with a molecular weight of 208.34 g/mol. It has a boiling point of 202-204°C and a flash point of 87°C. The liquid is soluble in most organic solvents, such as ethanol, acetone, and toluene, but insoluble in water. It has a high refractive index of 1.422 and a low viscosity of 0.004 Pa·s at 25°C.

The unique properties of allyltriethoxysilane make it an ideal choice for various applications in the chemical industry. Its organic group, allyl, contains a carbon-carbon double bond, which can undergo various chemical reactions, such as polymerization, oxidation, and substitution. The triethoxy group, on the other hand, provides good adhesion and compatibility with inorganic substrates, such as glass, ceramics, and metals.

Applications of Allyltriethoxysilane

Coupling Agent

Allyltriethoxysilane is widely used as a coupling agent in the synthesis of various organic-inorganic composites. It can react with inorganic substrates, such as silica, alumina, and titanium dioxide, to form covalent bonds. The resulting composites have improved mechanical properties, such as strength, toughness, and durability. The coupling reaction also enhances the adhesion between the organic and inorganic phases, preventing delamination and cracking.

Cross-linking Agent

Allyltriethoxysilane can also act as a cross-linking agent in the polymerization of organic monomers, such as acrylics, epoxies, and polyesters. The allyl group can undergo free-radical polymerization, forming a three-dimensional network structure. The triethoxy group, meanwhile, can react with the hydroxyl or carboxyl groups of the monomers, promoting the cross-linking reaction. The resulting polymers have improved thermal stability, chemical resistance, and adhesion.

Surface Modifier

Allyltriethoxysilane can also be used as a surface modifier in various coatings, adhesives, and sealants. It can form a thin film on the surface of substrates, such as glass, metal, and plastic, improving their hydrophobicity, oleophobicity, and antistatic properties. The film also enhances the adhesion between the substrate and the coating, preventing peeling and flaking.

Benefits of Allyltriethoxysilane

Allyltriethoxysilane offers several benefits to the chemical industry. It is a cost-effective and efficient coupling agent, cross-linking agent, and surface modifier, providing improved performance and durability to various products. It is also a versatile compound, compatible with various organic and inorganic substrates, enabling a wide range of applications. Additionally, it is a safe and environmentally friendly compound, with low toxicity and biodegradability, reducing the impact on human health and the environment.

Conclusion

Allyltriethoxysilane is a valuable compound in the chemical industry, offering unique properties and benefits for various applications. INNO Specialty Chemicals is a reliable manufacturer and supplier of allyltriethoxysilane from China, providing high-quality products and services to customers worldwide.
