Used primarily as a coupling agent to improve adhesion between organic polymers and inorganic materials. Commonly applied in the manufacturing of composites, coatings, and adhesives. Enhances the performance of fiberglass-reinforced plastics by promoting better bonding between the glass fibers and the resin matrix. Also utilized in surface treatment of fillers and pigments to improve dispersion and compatibility in polymer systems. In the automotive and construction industries, it is employed to modify surfaces of glass, metals, and minerals for improved durability and water resistance. Additionally, it plays a role in the production of sealants and elastomers, where it enhances mechanical properties and resistance to environmental factors.
