Used as a coupling agent to improve adhesion between organic and inorganic materials, such as glass, silica, or metals, and resins or polymers, especially in composites and coatings. Enhances the mechanical properties and durability of rubber and silicone systems by promoting strong bonding at interfaces. Commonly applied in sealants, adhesives, and paints to increase water resistance and corrosion protection.

Widely used in the production of composite materials, where it bonds glass fibers to the polymer matrix, thereby increasing the strength and service life of the product.

Also utilized in the production of silica-filled polymers and as a surface modifier for glass, metals, and fillers to improve dispersion and compatibility with polymer matrices. Additionally, it serves as a surface modifier in nanomaterials, such as silica gel or metal nanoparticles, to enable better dispersion in organic solvents, and in chemical sensors that require thiol (-SH) groups on the surface for binding target substances.
