Used primarily as a coupling agent in the production of composites and adhesives, it enhances the bonding between organic polymers and inorganic materials. It is applied in the surface treatment of glass fibers to improve their adhesion to polymer matrices, making it valuable in the manufacturing of reinforced plastics. Additionally, it serves as a key intermediate in the synthesis of organosilicon compounds, which are utilized in coatings, sealants, and elastomers to improve their durability and performance. Its role in modifying surfaces for better compatibility in hybrid materials is also significant in advanced material science applications.
