Usage
Silane Coupling Agents: Used for interfacial coupling between rubber and metal, resin and metal, or inorganic fillers and polymers, enhancing adhesion, water resistance, and mechanical properties.
Metal Surface Treatment and Corrosion Protection: Used for the surface modification of metals such as gold, silver, copper, and iron to form self-assembled monolayers, thereby preventing oxidation and corrosion while improving coating adhesion; also applied in the surface treatment of PCB circuit boards and electronic components.
Adhesives, Sealants, and Coatings: Improves the bonding strength of coatings, polyurethanes, and epoxy resins to glass, metals, and ceramics; enhances the resistance of coatings to humid heat and salt spray environments.
Organic Synthesis Intermediates: Used in the preparation of thiol-functionalized siloxanes and polysiloxanes, which serve as precursors for functional polymers and medical materials.
