Sodium silicate glass is a primary raw material for producing industrial adhesives, paperboard binders, and high-strength bonding agents due to its excellent adhesive properties and chemical stability.
Used as a binder in refractories, fire bricks, ceramic glazes, and heat-resistant coatings. It enhances thermal stability, structural strength, and surface hardness in high-temperature applications.
Acts as a key ingredient in detergent formulations, providing alkalinity, emulsification, dirt suspension, and anti-redeposition properties.
Functions as a binder in foundry sand molds and cores, ensuring better mold integrity and improved casting quality.
Serves as a base material for manufacturing sodium silicate liquid, specialty chemicals, catalysts, silica gels, and zeolite applications.
Used in cement formulations, waterproofing compounds, and concrete hardeners. It improves durability, resistance to moisture, and surface strength.
