Used as a coupling agent to improve adhesion between organic and inorganic materials, especially in coatings, sealants, and composite systems. Enhances durability and moisture resistance in silicone-based formulations. Commonly applied in surface modification of glass, metals, and fillers to promote better bonding with polymers. Also utilized in the production of silane-treated mineral fillers for plastics and rubber, improving dispersion and mechanical properties. Effective in adhesives and primers where strong interfacial strength is required.
