CAS 3069-40-7: Octyltrimethoxysilane
Description:Octyltrimethoxysilane, with the CAS number 3069-40-7, is an organosilane compound characterized by its long hydrophobic octyl chain and three methoxy groups attached to a silicon atom. This structure imparts unique properties, making it useful as a coupling agent, surface modifier, and adhesion promoter in various applications, including coatings, sealants, and composites. The octyl group enhances hydrophobicity, improving water resistance and compatibility with organic materials. Octyltrimethoxysilane can undergo hydrolysis in the presence of moisture, leading to the formation of silanol groups that can bond with silicate surfaces, promoting adhesion. It is typically a clear, colorless liquid with a low viscosity, and it is soluble in organic solvents. Safety considerations include handling it in well-ventilated areas and using appropriate personal protective equipment, as it may cause irritation upon contact with skin or eyes. Overall, its unique chemical structure and properties make it valuable in enhancing the performance of various materials in industrial applications.
