Dodecyltriethoxysilane

Description:

Dodecyltriethoxysilane, with the CAS number 18536-91-9, is an organosilane compound characterized by its long hydrophobic dodecyl chain and three ethoxy groups attached to a silicon atom. This structure imparts both hydrophobic and silane functionalities, making it useful in various applications, particularly in surface modification and as a coupling agent. The dodecyl group enhances the compound's compatibility with organic materials, while the ethoxy groups facilitate hydrolysis and bonding to silicate surfaces. Dodecyltriethoxysilane is typically a colorless to pale yellow liquid with a relatively low viscosity. It is soluble in organic solvents but reacts with moisture in the air, leading to the formation of silanol groups and subsequent polymerization. This property makes it valuable in creating hydrophobic coatings, improving adhesion in composite materials, and enhancing the durability of surfaces. 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.
