Self-Drying High-Temperature Silicone Resin
SR-6722 is a self-drying high-performance silicone resin produced through the polymerization of methylchlorosilane, phenylchlorosilane, and specialty functional silane monomers.
Its unique hybrid structure integrates organic functional groups with an inorganic Si-O backbone, giving the material a strong balance of thermal stability, chemical resistance, and excellent film-forming capability. It is specifically designed for demanding high-temperature protective coating systems where durability and long-term performance are critical.
