This chemical is widely used as a coupling agent in the production of composite materials. It enhances the adhesion between organic polymers and inorganic surfaces, making it valuable in coatings, adhesives, and sealants. It is also employed in the modification of silica nanoparticles to improve their compatibility with polymer matrices, which is crucial in advanced materials like nanocomposites. Additionally, it serves as a surface treatment for glass fibers to strengthen fiber-reinforced plastics. In the automotive and aerospace industries, it contributes to the durability and performance of composite parts. Its ability to bond dissimilar materials makes it essential in creating high-performance, multifunctional materials.
