Used primarily as a coupling agent in the production of composite materials, it enhances the adhesion between organic polymers and inorganic substrates. This chemical is particularly effective in improving the mechanical properties of fiber-reinforced plastics, such as strength and durability. It is also applied in the surface treatment of fillers and pigments to ensure better dispersion and compatibility within polymer matrices. Additionally, it finds use in coatings and sealants, where it contributes to enhanced moisture resistance and long-term stability. Its ability to form strong bonds with both organic and inorganic materials makes it valuable in industries like automotive, construction, and electronics.
