Sodium silicate solution is a widely used inorganic chemical valued for its excellent adhesion, binding strength, and protective performance. Composed of sodium, silicon, and oxygen in water, it spreads easily and forms durable, uniform coatings on a wide range of surfaces. It is extensively applied in construction as a cement and concrete additive to enhance strength, durability, and resistance to moisture and chemical exposure. Sodium silicate is also essential in the production of glass, ceramics, and refractory materials, improving thermal stability and corrosion resistance. In the textile industry, it functions as a finishing agent that enhances fabric smoothness and abrasion resistance, while in coatings and treatment formulations it provides effective waterproofing, corrosion protection, and fire-resistant properties. With its broad industrial applications and cost-effective performance, sodium silicate solution remains a key material in construction, manufacturing, textiles, and protective treatment sectors.

• P321: Specific treatment (see Section 4 of the SDS).
• P363: Wash contaminated clothing before reuse.
Hazards Not Otherwise Classified (HNOC):
• Environmental Hazards: This product is not classified as an environmental hazard, but care should be taken to avoid large quantities entering water systems. It can raise the pH of water, potentially harming aquatic life.
First Aid Measures:
• Inhalation: Move the affected person to fresh air immediately. If breathing is difficult, seek medical attention.
• Skin Contact: Immediately remove contaminated clothing. Rinse the skin with plenty of water for at least 15 minutes. Seek medical attention if irritation or burns persist.
• Eye Contact: Rinse eyes immediately with water for at least 15 minutes, lifting the eyelids occasionally. Seek medical attention immediately.
• Ingestion: Rinse mouth with water. Do not induce vomiting. Seek medical attention immediately if symptoms develop.
Handling and Storage:
- Store in a cool, well-ventilated area away from incompatible materials, heat sources, and direct sunlight.
- Use appropriate containment and handling equipment to prevent spills and leaks.
- Wear personal protective equipment, including gloves, goggles, protective clothing, and respiratory protection, when handling.
- Keep containers tightly closed and store in an inert gas atmosphere to prevent exposure to air.
- Follow all local regulations and guidelines for the safe handling and disposal of hazardous materials.
Emergency Measures:
- In case of a spill or leak, isolate the area and use appropriate materials to absorb and clean up the spill. Avoid contact with the spill and wear protective equipment.
- If a fire occurs, use appropriate fire-extinguishing agents and follow standard fire-fighting procedures. Evacuate the area if necessary.
- If exposed to the product, immediately remove contaminated clothing, rinse affected areas with water, and seek medical attention.
