What is Water Glass?
Water Glass (Sodium Silicate) — A Versatile Solution for Your Industry
Water glass, or sodium silicate (Na2SiO3), is a colorless chemical compound that is highly soluble in water and produces an alkaline solution. Due to its unique properties, this material is widely used across various industrial sectors.
Water glass is produced through a process of fusing soda ash (sodium carbonate) and silica sand at high temperatures (±1300°C). The result is a solution with high adhesive strength that is water-resistant and heat-resistant.
Key Advantages
- High adhesive strength: effective as a binding and adhesive agent.
- Water-resistant & fire-resistant: enhances the final product's resistance to water and heat.
- Multifunctional: suitable for adhesives, casting, textiles, detergents, surface protection, and waste treatment.
Common Applications
Water glass is widely used in foundry (metal casting), construction (cement and mortar), textiles, detergents, fireproof coatings, as well as in water and wastewater treatment processes.
