Used as a coupling agent in hybrid organic-inorganic materials, enhancing adhesion between organic polymers and inorganic surfaces such as glass, metals, and fillers. It is particularly effective in sol-gel processes where it promotes uniform network formation by improving compatibility between components. Commonly applied in coatings, sealants, and composite materials to increase durability, thermal stability, and moisture resistance. Also utilized in the development of functional surfaces with tailored properties such as hydrophobicity or corrosion protection.
