I. Definition and Classification

Silane coupling agents refer to a class of organosilicon compounds containing silicon-oxygen (Si-O) bonds, with molecular structures featuring one or more silicon atoms linked to organic groups. Based on functionality and application, silane coupling agents can be categorized into various types, such as amino silanes, mercapto silanes, and vinyl silanes. Among these, amino silanes are the most common, offering a balanced hydrophilic-hydrophobic property. They form stable chemical bonds on diverse substrates, significantly improving adhesion performance.
