Thiocyanato silanes are a family of organosilicon compounds containing a thiocyanate functional group (-SCN) attached to a silicon atom. They are used in a wide range of applications, such as adhesion promotion, surface modification, and as a starting material for the synthesis of other organosilicon compounds. Thiocyanato silanes are highly reactive and can form strong covalent bonds with various substrates, including metals, glass, ceramics, and polymers, through the thiocyanate group. They also offer excellent hydrolytic stability and thermal resistance, making them suitable for use in harsh environments. Additionally, their unique properties can be tailored to meet specific application requirements by modifying the molecular structure of the silane.
