Sodium water glass
The term sodium silicate is used to describe glassy, i.e. amorphous, water-soluble sodium silicates or their aqueous solutions that have solidified from a melt. Sodium silicates are mainly used in detergents, paper, water treatment and building materials (cement, mortars), as well as in paper recycling, paper coating and for metal degreasing. It is also found in soaps, detergents, ceramic products, paints and cosmetic preparations. It is not suitable for permanent moisture protection because, unlike potassium silicate, it gradually dissolves over time.
