Sodium Silicate
Liquid sodium silicate (water glass) specification reference: modulus, solid content, liquid packing and documents. Factory quotes for liquid / foundry continue on zzhchem.com.

Short answer
- Sodium silicate (water glass, Na₂O·nSiO₂, CAS 1344-09-8) is supplied as a liquid across a modulus range of 2.0–3.5 (LGY grades, Baumé 32.5–51.0) and as instant powder (LGS-20 and LGS-30 grades); solid lump or granule is quoted separately on request.
- Modulus is the specification that matters: it sets alkalinity, binding behaviour and cure characteristics, which is why concrete densifiers, foundry binders, drilling fluids and detergent systems each call for a different ratio rather than a generic grade.
- Zhongzhi Chemical manufactures and exports it from China in 200 L drums, 1,000 L IBC tanks and bulk tanker subject to destination and volume, with SDS downloadable and TDS and COA on request.

Product Overview
Sodium silicate, also known as water glass, is primarily reviewed here as a liquid silicate product line for industrial formulations, binder systems, construction materials, paper production and water treatment applications.
The key purchasing decision is normally modulus and solid content, followed by appearance, density, packing method, storage conditions, destination, and required documents.
If solid sodium silicate is required, buyers should state the requested form separately so the quotation can distinguish liquid supply from lump or granule supply.
