Application

Sodium Metasilicate reacts with acids to produce silica gel.

Cements and Binders - dehydrated sodium metasilicate forms cement or binding agent.

Pulp and Paper - sizing agent and buffer/stabilizing agent when mixed with hydrogen peroxide.

Soaps and Detergents - as an emulsifying and suspension agent.

Automotive applications - decommissioning of old engines (CARS program), cooling system sealant, exhaust repair.

Egg Preservative - seals eggs increasing shelf life.

Crafts - forms "stalagmites" by reacting with and precipitating metal ions.
