Description

Sodium Trisilicate Hydrate is a versatile inorganic silicate compound with significant industrial utility. Its primary value lies in its strong detergent, emulsifying, and binding properties, making it a key component in various manufacturing processes. This chemical is essential for industries such as detergents, ceramics, construction, and water treatment, where its ability to control pH and suspend particulates is highly valued.

Application

• Detergent & Cleaning Formulations: Acts as a powerful builder and emulsifying agent in industrial and institutional cleaning products, enhancing soil removal and water softening.
• Ceramics & Refractories: Serves as a binder and fluxing agent in the production of ceramics, tiles, and refractory materials, improving green strength and final product integrity.
• Construction Materials: Used in specialty cements, concrete sealants, and fireproofing compounds for its adhesive and setting properties.
• Water Treatment: Functions as a corrosion inhibitor and scale control agent in boiler water and cooling tower systems.
• Metal Surface Treatment: Employed in metal cleaning and degreasing processes prior to painting, plating, or further fabrication.
• Adhesives & Binders: Utilized in the formulation of paper coatings, cardboard, and other composite materials as an inorganic binder.
• Textile Processing: Acts as a stabilizer and pH buffer in scouring and bleaching baths for fabrics.

Quality Control

Our Sodium Trisilicate Hydrate is manufactured under strict quality management protocols. Each batch undergoes rigorous analytical testing to ensure consistency and compliance with relevant industrial specifications. Key parameters such as silicate ratio (SiO2:Na2O), assay, and impurity levels are controlled. Certificates of Analysis (COA) documenting these results are available upon request to support your quality assurance and regulatory needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). Due to its hygroscopic nature, the container must be kept tightly sealed after each use to prevent moisture absorption and caking. Keep away from strong acids.
