Frequently Asked Questions
What is sodium silicate used for?
Sodium silicate — commonly called water glass — is used in detergent formulation, paper and board adhesives, foundry sand binding, construction chemicals, and refractory cements. We supply the commercial liquid grade (ratio ~2.0:1 SiO2:Na2O) to buyers across these industries in South India.
Is sodium silicate the same as water glass?
Yes. Water glass — sometimes liquid glass — is the common name for sodium silicate in solution. The grade we stock is a clear viscous liquid, commercial grade, with an SiO2:Na2O weight ratio of 1.95–2.10.
What is the CAS number and HSN code of sodium silicate?
Sodium silicate is CAS 1344-09-8. For GST and customs classification in India, it falls under HSN code 2839 19 00.
What is the specification of commercial-grade liquid sodium silicate?
Our commercial liquid grade runs total solids 44–47% by mass, Na2O 14.5–15.5%, SiO2 29.0–31.0%, and specific gravity 1.55–1.59 at 30°C, per the manufacturer's published specification. A technical data sheet (TDS) and MSDS are available on request.
Where can I buy liquid sodium silicate in bulk in Chennai?
We stock liquid sodium silicate at our Redhills, Chennai warehouse and have traded industrial chemicals since 1997. Supply is in carboys or by road tanker for bulk; order sizes depend on packaging and current stock. Call or WhatsApp +91 86087 80096 for a quote.
Whose sodium silicate does SPC distribute?
We distribute liquid sodium silicate manufactured by GACL — Gujarat Alkalies and Chemicals Limited, a Government of Gujarat enterprise with ISO certification. The figures on our TDS come from GACL's published specification for the commercial liquid grade.
