Sodium Silicate Liquid 38-40 Bé

Sodium Silicate Liquid 38-40 Bé (CAS 1344-09-8, molecular formula Na2SiO3) is a formulation raw material used by detergent, personal care and industrial cleaning manufacturers who need stable active matter and reproducible performance. China Chemicals supplies it at Solids 35 – 40% in pack sizes from 1 L through to 200 L Drum, so laboratory trial quantities and full production volumes can be sourced from the same specification.

It is also traded as Water Glass, Liquid Glass, Sodium Metasilicate Solution. Every consignment ships with a batch-specific Certificate of Analysis and the current Safety Data Sheet, and material is stored and picked under stock rotation so you receive product well inside its shelf life.

Typical applications

Detergent builder and anti-redeposition agent
Adhesive for corrugated board and cartons
Soil stabilisation and grouting
Foundry sand binder in casting
Silica gel and catalyst manufacture
