butyl(triethoxy)silane

Description:
Butyl(triethoxy)silane, with the CAS number 4781-99-1, is an organosilicon compound characterized by its silane structure, which includes a butyl group and three ethoxy groups attached to a silicon atom. This compound is typically a colorless to pale yellow liquid with a distinctive 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. Butyl(triethoxy)silane is often used as a coupling agent, adhesion promoter, or surface modifier in various applications, including coatings, sealants, and adhesives. Its ability to enhance the bonding between organic materials and inorganic substrates makes it valuable in the manufacturing of composites and in the treatment of surfaces to improve durability and resistance to environmental factors. Additionally, it exhibits good compatibility with a range of organic solvents, making it versatile in formulation chemistry. Safety precautions should be observed when handling this compound, as it can be irritating to the skin and eyes.
