Description
Sodium Silicate, commonly known as Water Glass, is a colorless to light blue liquid or white solid composed of sodium oxide (Na₂O) and silicon dioxide (SiO₂). It is valued for its excellent binding, sealing, and corrosion-inhibiting properties and is used across a wide range of industrial applications.
