• As an inorganic binder for refactory fillers and pigments, like precision investment castings.
• As a second backup casting coating. It cures faster than silica system.
• May be hydrolyzed to form silicon dioxide (silica).
• As a binder in zinc-rich (corrosion resistant) coating.
• As a starting material for sol-gel process.
• As a crosslinking agent for silicone sealant.
• As a drying agent in sealing compositions.
• As a chemical intermediate.
