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 particularly effective in improving the performance of glass fiber-reinforced plastics by promoting better bonding between the fibers and the resin matrix. Additionally, it is utilized in surface treatment applications for metals, ceramics, and glass to increase durability and resistance to environmental factors. Its role in modifying surfaces for improved compatibility with various materials makes it essential in industries such as automotive, construction, and electronics.
