CAS 2943-75-1: Octyltriethoxysilane

Description: Octyltriethoxysilane, with the CAS number 2943-75-1, is an organosilicon compound characterized by its silane structure, which includes an octyl group and three ethoxy groups attached to a silicon atom. This compound is typically a colorless to pale yellow liquid and is known for its hydrophobic properties, making it useful as a surface modifier and coupling agent. Octyltriethoxysilane can enhance the adhesion of organic materials to inorganic substrates, such as glass and metals, by forming a siloxane bond upon hydrolysis and condensation. It is often employed in applications such as coatings, sealants, and adhesives, where improved water repellency and durability are desired. Additionally, it can be used in the formulation of silicone-based materials and as a precursor in the synthesis of silica nanoparticles. 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.
