Sodium Metasilicate Pentahydrate

Description: Sodium Metasilicate Pentahydrate (Na₂SiO₃·5H₂O) is an important chemical compound, appearing as solid white granular crystals, hygroscopic, and soluble in water. It has cleaning, binding, and anti-corrosion properties, widely applied in various industries and daily life.

• Detergents: Used in cleaning product formulations thanks to its ability to break down grease and stains, while enhancing solution stability.
• Cement & adhesives: Forms durable solids when reacting with water, helping bind construction materials such as bricks, stones, concrete, and plaster; also used as a waterproofing and anti-corrosion agent for concrete surfaces.
• Egg preservation: A coating of sodium metasilicate on eggshells prevents bacteria, gases, and moisture from penetrating, extending shelf life without affecting quality.
• Handicrafts: Applied to create “stalactites” from metal ions and used as a glue called “soluble glass” for bonding paper, fabric, wood, and metal.
• Automotive industry: Used to deactivate old engines, seal cooling systems, and repair exhaust leaks.
