Butyltrimethoxysilane is widely used as a coupling agent in the production of adhesives, sealants, and coatings. It enhances the bonding between organic polymers and inorganic materials, such as glass, metals, and minerals, improving durability and water resistance. In the construction industry, it is applied to modify concrete and mortar, increasing their strength and reducing water absorption. It also serves as a surface treatment agent for fillers and pigments, ensuring better dispersion and stability in various formulations. Additionally, it is utilized in the manufacturing of silicone resins and as a crosslinking agent in silicone rubber production.
