Used as a coupling agent in adhesives, sealants, and composite materials to improve adhesion between organic polymers and inorganic surfaces like glass, metals, and fillers. Enhances mechanical strength and durability in fiberglass-reinforced plastics and electrical insulation systems. Applied in coatings and primers to increase corrosion resistance and moisture protection. Also utilized in the production of silane cross-linked polyethylene (XLPE) for wire and cable insulation. Common in foundry resins and mineral-filled composites to improve dispersion and bonding.
