Silanes are silicon-based compounds with organo-functional groups that enable them to chemically bond with both organic polymers and inorganic surfaces. This makes silanes extremely useful as adhesion promoters, coupling agents, and surface modifiers across a wide range of materials and industries.

Through hydrolysis and condensation reactions, silanes form strong silicon-oxygen bonds with surfaces such as glass, metal, and minerals. These bonds can significantly improve adhesion, dispersion, moisture resistance, and mechanical properties.
