Triisopropoxysilane 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, improving durability and performance. In the construction industry, it is applied in waterproofing treatments for concrete and masonry, providing long-lasting protection against moisture. Additionally, it serves as a precursor in the synthesis of siloxanes and other silicon-based compounds, which are essential in manufacturing silicone resins and elastomers. Its role in surface modification also makes it valuable in the preparation of nanomaterials and composites, where it improves compatibility and dispersion of fillers.
