This chemical is primarily used as a coupling agent in the production of composite materials. It enhances the adhesion between organic polymers and inorganic substrates, making it valuable in coatings, adhesives, and sealants. It is also employed in surface treatment of glass fibers and minerals to improve compatibility with resin systems. Additionally, it finds application in the modification of silica fillers in rubber and plastic industries to enhance mechanical properties and durability. Its ability to form stable bonds between dissimilar materials makes it a key component in advanced material engineering.
