Product Description
Sodium Silicate Solution is an alkaline, water-soluble inorganic chemical consisting of sodium oxide (Na₂O) and silicon dioxide (SiO₂) in varying proportions. It is commonly known as Liquid Water Glass.
It is widely used in detergent manufacturing, water treatment, cement and construction chemicals, refractory binders, foundry applications, paper manufacturing and industrial cleaning formulations.
Description :
Sodium silicates are colorless glassy or crystalline solids, or white powders. Except for the most silicon-rich ones, they are readily soluble in water, producing alkaline solutions. When dried up it still can be rehydrated back in water. Sodium silicates are stable in neutral and alkaline solutions.
Synonyms :
- Silicic acid (H2O3Si), disodium salt, pentahydrate.
- Silicic acid (H2O5Si2), disodium salt.
- Silicic acid (H2O7Si3), disodium salt.
- Silicic acid (H2O9Si4), disodium salt.
- Silicic acid (H4O4Si), tetrasodium salt.
- Silicic acid (H7O7Si2), hexasodium salt.
- Sodium silicate.
Uses :
Sodium Silicate is used in soaps detergents and in the manufacture of silica gel. It is used as a cement, binder, filler and adhesive. And also used as a wall coating, in concrete, fire proofing material and as a sealant. It is also used to preserve eggs and wood.
Storage and Handling
Store in tightly closed, alkali-resistant HDPE or compatible steel containers. Protect from freezing, excessive heat and contamination with acids. Avoid contact with aluminium, zinc and other alkali-sensitive materials.
Use chemical-resistant gloves and eye protection when handling concentrated solutions.
One important question: Which grade of Sodium Silicate Solution do you require — alkaline grade (SiO₂:Na₂O ratio 2.0), neutral grade (3.2–3.3), or general industrial liquid grade? This determines the correct specifications and applications. Email us ::: rxmarinegroup @ gmail.com

Sodium Silicate is used in soaps detergents and in the manufacture of silica gel. It is used as a cement, binder, filler and adhesive. And also used as a wall coating, in concrete, fire proofing material and as a sealant. It is also used to preserve eggs and wood.
APPLICATION::
It's used in construction, detergents, textiles, and even food preservation.
Here's a more detailed look at its uses:
Construction:
Concrete and Cement Admixture:
- Sodium silicate increases the strength and durability of concrete and acts as a sealant, preventing water penetration.
Soil Stabilization:
- It's used to stabilize soil at construction sites, particularly for roads and foundations.
Fireproofing:
- Sodium silicate acts as a fire retardant, adding a layer of protection against fire damage to buildings.
Detergents:
Builder:
- It helps remove hard water ions and control alkalinity, making detergents more effective and preventing fabric damage.
Soap Manufacturing:
- Sodium silicate can be used as a filler and to increase the hardness of soap bars.
Sodium silicate solution, also known as water glass or liquid glass, is a colorless, viscous, inorganic salt solution formed by dissolving sodium oxide (Na₂O) and silicon dioxide (SiO₂) in water. It's a versatile compound used in various applications, including adhesives, detergents, and as a component in drilling fluids.
- Paper and Cardboard: It acts as a binder and adhesive in paper and cardboard production.
- Water Treatment: Sodium silicate can be used to remove heavy metals and other contaminants from water.
- Textiles: It's used as a flame retardant and sizing agent.
- Food Preservation: It can be used to preserve eggs and other food items by creating a protective coating.
- Arts and Crafts: It's used in various creative projects due to its binding and adhesive properties.
- Automotive Repair: In some cases, it's used to repair engine blocks and head gaskets.
- Dentistry: It's used as a cement for fillings and bonding dental prostheses.
- Wastewater Treatment: It can be used as a flocculent in wastewat er treatment units.
