Construction use cases
Formulation input for mineral systems; also used in certain hardener/sealer approaches depending on grade.
Product Construction Chemicals
Sodium Silicate Solution
Alkaline sodium silicate solution (“water glass”) supplied to specification for construction formulations, surface treatments, and selected process applications. Modulus (SiO2/Na2O) and solids content per requirement.
✓ Modulus per grade
✓ Solids per spec
✓ Alkaline binder/SiO₂ source
✓ Drums • IBC • bulk
✓ SDS/COA/TDS on request
Packaging: drums / IBC / bulk (as applicable)
Documentation: SDS / COA / TDS on request
Lead time depends on lane, spec & volume
For construction and formulation use, the two most important specification inputs are modulus (SiO2/Na2O ratio) and solids content. If you share your target values (or the name of an existing grade), we can align the correct supply lane and documentation set.
Applications
Sodium silicate solution is used as an alkaline binder, hardener input, and SiO2 source across construction chemicals and various industrial processes. Exact performance depends on modulus, solids, and how the product is formulated into the system.
- Binder / additive input in construction formulations (mortars, specialty blends)
- Surface treatment and sealing (cementitious surfaces; application method dependent)
- Mineral-based coatings and fire/heat-related systems (where silicates are specified)
- Process applications requiring silicates (alkaline SiO2 source)
- Adhesive, paper, and foundry-related uses (industry-dependent requirements)
Formulation role
Provides alkalinity and soluble silicate; can influence set behavior, viscosity, and film/mineral network formation.
Why grade matters
Modulus and solids directly impact viscosity, reactivity, and end performance. Specify both when possible.
If you’re using sodium silicate as a surface treatment, share substrate type (new/aged concrete, moisture condition), and the performance goal (dust control, densification, sealing, adhesion promotion) so we can match a suitable grade.
Why sodium silicate solution is specified
In mineral and construction chemistry, sodium silicate is valued for its alkalinity and soluble silicate content. Performance is grade-dependent and tied to how it is used in the formulation or treatment method.
Soluble silicate source
Provides SiO2 in soluble form for mineral networks, coatings, and specialty blends.
Alkalinity
High pH supports certain reactions and stability behaviors; requires appropriate handling controls.
Binder functionality
Used as a binder or binding aid in mineral systems depending on formulation approach.
Process versatility
Liquid format supports metering, mixing, and consistent dosing in production environments.
For repeat procurement, we recommend specifying: modulus, solids, typical viscosity range (or handling preference), and any impurity limits relevant to your application.
Grade selection framework
Sodium silicate solutions are commonly identified by their modulus (SiO2/Na2O ratio) and solids content. These parameters influence viscosity, alkalinity, reactivity, and end performance in the target system.
Modulus (SiO₂/Na₂O)
Higher/lower ratios shift alkalinity and silicate availability. Tell us the target ratio used in your formulation.
Solids content
Impacts transport economics, viscosity, and dosing. Specify your target solids (%) or existing spec.
Viscosity/handling
Affects pumpability and mixing. Share if you need a “low viscosity” or “standard viscosity” preference.
Common procurement questions
- Do you require a specific modulus (SiO2/Na2O) and tolerance?
- What solids % do you need at receipt (and can you dilute on-site)?
- Are there impurity limits that matter (chlorides, insolubles, metals)?
- Is the use case binder/formulation input or surface treatment (different priorities)?
If you send an existing COA/TDS from your current supplier, we can match the same modulus/solids profile for a like-for-like quote.

Indicative technical data (example fields)
Example fields for typical COA/TDS. Exact values depend on the grade selected and should be confirmed on the supplied documentation.
| Property | Typical description | Why it matters |
|---|---|---|
| Chemical name | Sodium silicate solution (liquid) | Confirms product identity and regulatory documentation. |
| Modulus | SiO2/Na2O ratio (per spec) | Primary performance lever for alkalinity/reactivity/viscosity behavior. |
| Solids content | % by mass (per spec) | Affects dosing, viscosity, and shipping economics. |
| Density | Grade-dependent | Supports mass/volume conversions and metering calculations. |
| Viscosity | Grade-dependent | Important for pumpability and mixing behavior. |
| pH | Alkaline (typical) | Handling and compatibility; influences formulation stability. |
| Insolubles | By spec (if required) | Important for coatings, surface treatments, and filtration-sensitive processes. |
Specifications may vary depending on batch, origin, and packaging selection. For critical formulation performance, request a sample and validate in a pilot.
Handling & storage guidance
Sodium silicate solution is alkaline. Proper handling is required to protect personnel and maintain product quality. Always follow the supplied SDS and your internal EHS procedures.
PPE (typical)
Gloves and eye/face protection; protective clothing as required by risk assessment.
Storage
Keep containers sealed. Store away from incompatible chemicals per SDS. Protect from contamination.
Handling notes
Avoid splashing. Use compatible pumps/hoses and keep transfer systems clean to prevent gel/solid formation.
If your site has specific storage rules (secondary containment, temperature limits, material restrictions), include them in the inquiry so we can align packaging and handling expectations.
Supply & procurement details

Documentation set
SDS/TDS on request. COA availability depends on grade and lane.
Lead time
Depends on grade, packaging, labeling, and order size. Confirmed on quotation.
Quality alignment
For formulation consistency, specify modulus, solids, and any impurity limits that impact your process.

FAQ
Common technical and procurement questions for sodium silicate solution.
What is “modulus”?
Modulus is the SiO2/Na2O ratio used to describe sodium silicate grades. It’s one of the primary parameters that affects alkalinity, reactivity, and viscosity behavior in formulations.
What solids % should I request?
Solids selection depends on your dosing strategy and handling capability. Higher solids can improve shipping economics but may increase viscosity. Share your target formulation and transfer setup for guidance.
Do you provide SDS/COA/TDS?
Yes. Documentation is available on request and depends on grade and supply lane.
Can it be used as a surface sealer/hardener?
Sodium silicate solutions are used in some surface treatment approaches, but performance is application-dependent. Share substrate type, condition, and objective so we can align the correct grade and handling expectations.
How should I store it?
Store sealed and follow SDS guidance. Keep transfer equipment clean and compatible. Avoid contamination that can affect stability.
What speeds up quoting?
Modulus, solids, packaging preference, monthly volume, and destination. If you have an existing TDS/COA, attach or summarize it.
