Used as a coupling agent in composite materials, enhancing adhesion between organic polymers and inorganic surfaces such as glass, metals, and minerals. Commonly applied in sealants, adhesives, and coatings to improve durability and moisture resistance. Also utilized in the production of glass fiber-reinforced plastics, where it promotes stronger bonding between the resin matrix and glass fibers. Its reactive ureido group enables compatibility with various polymer systems, making it effective in improving mechanical properties and long-term stability in demanding environments. Frequently employed in electronics and construction industries for surface modification and primer formulations.
