Used primarily as a coupling agent in the production of composite materials, it enhances the adhesion between organic polymers and inorganic substrates. It is commonly applied in coatings, adhesives, and sealants to improve durability and performance. In the electronics industry, it is utilized for surface modification of fillers and reinforcements in encapsulants and molding compounds. Additionally, it finds use in the treatment of glass fibers to improve their compatibility with resin matrices in fiber-reinforced plastics. Its silane functionality allows it to bond effectively with glass, metals, and minerals, making it valuable in various industrial applications.
