Sodium silicate (liquid glass) Used in cleaning, inorganic adhesives, surface treatment, and several other industrial processes. When the correct modulus (SiO₂/Na₂O ratio) is used and dilution is controlled, the product dissolves/disperses more stably, reducing unwanted precipitation.
Sodium silicate / water nitCAS commercial solutions are usually attached 1344-09-8 (Liquid glass). Loc Thien B2B: quotation on request, COA/MSDS per batch — see LCT product page.
- Determine the modulus (SiO₂/Na₂O ratio) and concentration before scaling the process.
- Dilute with appropriate water, stirring well; avoid sudden, uncontrolled mixing with strong acids.
- Keep tightly sealed to prevent freezing/caking; avoid contact of PPE with alkaline solutions.
This is a summary of the liquid silicate usage process for technical reference and procurement purposes. Lot specifications are taken from the COA; your plant's SOP remains the standard operating procedure.
What is liquid silicate used for?
Common applications:
- Inorganic adhesives/glues, for molding (depending on the formulation).
- Cleaning agents and pH-alkaline building blocks in industrial detergents.
- Surface treatment, waterproofing/mineralization (custom formula).
- Assisting in certain processes related to paper, ceramics, and light metallurgy (as specified).
Each industry has different module ranges and concentrations — don't copy dosages from one industry to another without jar-testing/pilot testing.
Specifications to inquire with the supplier.
| Parameter | Why is it important? | Note |
|---|---|---|
| SiO₂/Na₂O Module | Effects on viscosity, reactivity, and alkalinity. | As indicated on the COA/spec |
| Solid content / Baumé | Dilution and standardization | Compare lots |
| Density, viscosity | Pump, stir, store | Temperature dependent |
| External inspection | Precipitation/cloudiness detected | Observe the goods upon receipt. |
| CAS / designation | Securely synchronize records. | Water glass solution ~1344-09-8 |
Instructions for use (refer to the instructions).
- Spec confirmation: Module, concentration, and packing (drum/IBC/tanker truck) as per order.
- Dilute (if necessary): Add silicate to the stirring water (or according to the factory's SOP); avoid pouring water in large quantities into the thick, viscous mass.
- Quantitative: Use a suitable pump/viscosity gauge; record the batch.
- Mixing: The order of acids, salts, polymers, etc., according to the pilot — incorrect order can easily lead to gelling/precipitation.
- Pipe cleaning: Rinse thoroughly, avoiding letting the water dry and stick to the sides.
- Inspect finished products/processes: pH, adhesion, clarity… according to internal QC.
Safety and storage
- Alkaline solution: PPE (glasses, gloves, protective gear), eyewash station.
- Avoid sudden exposure to concentrated acids; neutralize in a controlled manner.
- Keep tightly sealed, store in a dry place, and avoid freezing, as this will alter its properties.
- MSDS by batch; spills: mechanical recovery + neutralization according to MSDS.
Top Q&A
What is liquid sodium silicate CAS?
With liquid glass/sodium silicate solution, CAS profiles are commonly used. 1344-09-8The anhydrous metasilicate salt form has a different CAS number — do not mix them up when declaring.
What is the effect of the SiO₂/Na₂O module?
High/low modulus modulus changes alkalinity, viscosity, and reaction behavior. Choose the modulus based on industry standards, not just on "density".
Why does precipitation/gel formation occur during mixing?
This is often due to a sudden drop in pH (acidity), incorrect mixing order, hard/impure water, or sitting for too long after mixing. Pilot small amounts before scaling.
Can it be mixed with NaOH or acid?
There may be control measures in the formula. Improper mixing can easily generate heat/precipitate—causing residue to adhere to the SOP and MSDS.
How is industrial packaging done?
Depending on the supplier: drums, IBCs, tank trucks. Choose according to pump capacity and frequency of use.
