This chemical is primarily used as a coupling agent in the production of composites and adhesives. It enhances the bonding between organic polymers and inorganic materials, such as glass, metals, and minerals. In the coatings industry, it improves adhesion and durability of paints and protective layers on various substrates. It is also employed in the modification of silica surfaces, making them more compatible with organic matrices in rubber and plastic manufacturing. Additionally, it finds application in the preparation of silane-modified polymers, which are used in sealants and elastomers for improved mechanical properties and weather resistance.
