Need Sodium Silicate (Water Glass) in bulk? ChemicalDekho connects you with top manufacturers like Kiran Global Chem and Captain Polyplast. Source Neutral and Alkaline grades tailored for detergents, foundry molds, and construction.
Sodium Silicate (CAS 1344-09-8) is a workhorse chemical valued for its binding and adhesive properties. It is extensively used as a deflocculant in ceramic slurries, a binder in foundry sand molds, and a builder in detergent powders to prevent corrosion. Listings include both liquid solutions (40-50%) and solid glass lumps.
The platform ensures verified supply with specific SiO2:Na2O ratios (weight modulus) to match your application, backed by consistent density and viscosity data.

Causes skin irritation and serious eye damage due to high alkalinity (pH > 11). dries to form sharp glass-like residue.
The ratio refers to the weight proportion of Silica (SiO2) to Sodium Oxide (Na2O). Higher ratios (3.2) are 'Neutral' and better for adhesives; lower ratios (2.0) are 'Alkaline' and better for detergents.
It is generally non-toxic but highly alkaline, which can cause chemical burns to skin and eyes.
Yes, when applied to concrete, it reacts with free calcium to form a hard, insoluble gel that fills pores and seals the surface.
It provides alkalinity for cleaning, keeps dirt suspended, and protects washing machine parts from corrosion.
