Used as a surface modifying agent to introduce cyanide functional groups onto various substrates, enhancing adhesion properties in coatings and composites. Commonly applied in the production of advanced materials, such as glass, silicon wafers, and metal oxides, to improve surface reactivity and bonding with polymers or other materials. It also plays a role in creating self-assembled monolayers (SAMs) for nanotechnology applications, including biosensors and microelectronics. Its trichlorosilane group enables strong covalent bonding with hydroxylated surfaces, making it valuable in creating durable and chemically stable interfaces.
