Sodium Silicate Solution

Sodium silicate, also known as water glass, has many uses, including:

• Refractory linings: It is used as a binder of the sand when doing sand casting of all common metals. It allows for the rapid production of a strong mold or core
• Construction: Used in adhesives for bonding paper, corrugated boxes, glass, porcelain, leather, textiles, and stoneware. It's also used as a chemical grouting material, especially when drilling permeable formations. 
• Detergents: Used in dishwasher and laundry detergents to soften hard water, prevent corrosion, and improve the durability of detergent granules. 
• Water treatment: Used in wastewater treatment plants as an iron flocculant and an alum coagulant. NSF certifies it for use in drinking water treatment. 
• Paper industry: Used as a deinking agent. 
• Automotive repair: Used to seal leaks in head gaskets. 
• Food preservation: Used in food preservation, homebrewing, and aquaculture. 
• Hand-dyeing: Used as a fixative in hand-dyeing. 
• Pottery: Used in pottery. 
• Pulp and paper industry: Used as a transition metal ion chelate, a pH buffer, a stabilizer, a surface active agent and penetrant, and as a corrosion control agent. 
• Magic crystal garden toys: Used in the 1980's to create magic crystal garden toys.
