Description
Sodium Silicate Liquid 38-40 Bé
We are a bulk sodium silicate supplier of 38-40 Bé liquid water glass. 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

What Is Sodium Silicate (Water Glass)?
Sodium silicate liquid (water glass) is a versatile alkaline solution of sodium oxide and silica, supplied here at 38-40 Baumé (a measure of solution density). It is a clear, viscous liquid known for its adhesive, bonding, sealing and detergent-building properties. As a sodium silicate supplier we provide a 38-40 Bé grade used across adhesives, detergents, construction, water treatment and many industrial processes, prized for being effective, inexpensive and non-toxic in use.
Applications
Sodium silicate is used as an adhesive and bonding agent (for paper, cardboard and foundry cores), as a detergent builder and alkalinity source, in construction as a sealer, hardener and soil stabiliser, in water treatment as a coagulant aid and corrosion inhibitor, and in the manufacture of silica gel and other silicates. It is also used in metal casting, drilling fluids and fire protection.
In detergents it provides alkalinity and helps protect metal surfaces, working alongside builders such as STPP and surfactants.
Handling & Safety
Sodium silicate is alkaline and causes skin irritation and serious eye damage on contact, so wear eye protection and gloves and avoid splashes. It is far milder than caustic soda, but concentrated solution should still be handled with care. It is not flammable.
Store it in closed containers, since it can absorb carbon dioxide and skin over or gel on prolonged air exposure, and keep it from freezing. Follow the current Safety Data Sheet.
Frequently Asked Questions
What is sodium silicate used for?
As an adhesive and bonding agent, a detergent builder, a construction sealer and soil stabiliser, a coagulant aid and corrosion inhibitor in water treatment, and in silica-gel and silicate manufacture.
Why is it called water glass?
When a concentrated sodium silicate solution dries, it forms a hard, glassy film, which is the origin of the traditional name “water glass”.
What does 38-40 Bé mean?
Baumé (Bé) is a scale of solution density. It indicates the concentration and viscosity of the sodium silicate solution, which affects how it is used.
