CAS 18765-38-3: Tetrakis(2-butoxyethyl) orthosilicate

Description: Tetrakis(2-butoxyethyl) orthosilicate, with the CAS number 18765-38-3, is an organosilicon compound characterized by its silicate structure, where a silicon atom is bonded to four 2-butoxyethyl groups. This compound is typically a colorless to pale yellow liquid and is known for its low viscosity and good solubility in organic solvents. It exhibits properties such as hydrolytic stability and the ability to form silicate networks upon curing, making it valuable in applications like coatings, adhesives, and sealants. The presence of butoxyethyl groups enhances its compatibility with various organic materials, while also providing flexibility and durability to the resulting polymeric materials. Additionally, tetrakis(2-butoxyethyl) orthosilicate can undergo hydrolysis in the presence of moisture, leading to the formation of silica, which contributes to its utility in creating silica-based composites. 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.
