CAS 78-07-9

Ethyltriethoxysilane

Description:

Ethyltriethoxysilane, with the CAS number 78-07-9, is an organosilicon compound characterized by its silane structure, which includes an ethyl group and three ethoxy groups attached to a silicon atom. This compound is typically a colorless to pale yellow liquid with a mild odor. It is known for its reactivity, particularly in hydrolysis, where it can form silanol groups upon exposure to moisture, leading to the formation of siloxane networks. Ethyltriethoxysilane is often used as a coupling agent, adhesion promoter, and surface modifier in various applications, including coatings, sealants, and composites. Its ability to bond organic materials to inorganic surfaces makes it valuable in enhancing the durability and performance of materials. Additionally, it exhibits good compatibility with a range of organic solvents and can improve the hydrophobicity of surfaces. Safety considerations include handling it in well-ventilated areas and using appropriate personal protective equipment, as it can be irritating to the skin and eyes.
