CAS 5157-75-5: Octadecylmethyldichlorosilane
Description:Octadecylmethyldichlorosilane, with the CAS number 5157-75-5, is an organosilicon compound characterized by its long hydrophobic alkyl chain, which consists of 18 carbon atoms. This structure imparts significant hydrophobic properties, making it useful as a surface modifier in various applications, including coatings and adhesives. The presence of dichlorosilane functional groups allows for the formation of siloxane bonds with surfaces, enhancing adhesion and providing water-repellent characteristics. Typically, it appears as a colorless to pale yellow liquid and has a relatively low volatility. Its reactivity is primarily due to the chlorosilane groups, which can hydrolyze in the presence of moisture, leading to the formation of silanol groups and subsequent polymerization. This compound is often utilized in the modification of silica and other inorganic surfaces to improve their compatibility with organic materials. Safety precautions should be taken when handling this substance, as it can be corrosive and may pose health risks if inhaled or in contact with skin.
