Description

Potassiumsodiumsilicate CAS NO 37328-88-4 is a versatile inorganic compound, a mixed alkali silicate known for its strong alkaline properties and solubility in water. This material is critical for industrial processes requiring a stable, reactive alkali source with unique binding and fluxing characteristics. It is essential for manufacturers in sectors such as detergents, construction, ceramics, and metallurgy, where its dual alkali nature provides performance advantages over single-component silicates.

Application

• Detergent & Cleaning Formulations: Acts as a powerful builder, emulsifier, and corrosion inhibitor in industrial and institutional cleaning products.
• Ceramic & Glass Production: Serves as a high-temperature flux and binder in glazes, enamels, and specialty glass batches.
• Construction Materials: Used as an adhesive and hardening accelerator in cementitious products, refractory binders, and acid-resistant coatings.
• Metallurgy & Foundry: Functions as a binder in sand casting molds and cores, and as a slag modifier.
• Water Treatment: Employed as a coagulant aid and for corrosion control in industrial water systems.
• Fire Protection: A key component in intumescent paints and fire-resistant coatings and sealants.
• Textile & Paper Processing: Used as a stabilizer, bleach aid, and for pulp processing.
• Catalyst & Adsorbent Support: Provides a high-surface-area, alkaline substrate for various chemical catalysts.

Quality Control

Our Potassiumsodiumsilicate is manufactured under strict quality management systems to ensure batch-to-batch consistency and reliability. Quality is verified through rigorous testing of key parameters including alkalinity, silicate ratio, viscosity, and solids content. A Certificate of Analysis (COA) documenting these results is provided with every shipment to guarantee compliance with your technical requirements and industry standards.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). Keep away from strong acids and incompatible organic solvents. Due to its alkaline nature, ensure containers are sealed to prevent absorption of atmospheric carbon dioxide.
