Description

Silicate CAS NO 12627-13-3 is a versatile class of inorganic compounds, typically sodium or potassium salts, known for their binding, adhesive, and pH-buffering properties. These materials are essential for providing structural integrity, chemical resistance, and thermal stability in a wide range of industrial formulations. They are a critical raw material for manufacturers in the construction, detergents, ceramics, and foundry industries seeking reliable performance and consistent quality.

Application

• Construction & Cement: As a binder and hardening accelerator in specialty cements, concrete sealers, and refractory materials.
• Detergents & Cleaners: Serving as a builder to soften water, suspend soil, and control pH in industrial and institutional cleaning formulations.
• Foundry & Metal Casting: Used as a core binder in sand molds to provide high-temperature strength and dimensional accuracy.
• Ceramics & Glass: Acting as a flux to lower melting temperatures and improve the durability of glazes, enamels, and glass batches.
• Paper & Pulp Industry: Functioning as a coating pigment adhesive and a de-inking agent in paper recycling processes.
• Water Treatment: Utilized as a corrosion inhibitor and scale preventative in boiler and cooling water systems.
• Adhesives & Sealants: Providing enhanced bonding strength and fire resistance in inorganic adhesive systems.

Quality Control

Our silicate products are manufactured under strict quality management systems to ensure batch-to-batch consistency and performance. Key parameters such as silicate ratio (SiO₂:M₂O), solids content, viscosity, and density are rigorously controlled. Certificates of Analysis (COA) documenting these specifications are available for every shipment to support your quality assurance protocols.

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. For liquid grades, protect from freezing. Containers should be kept tightly sealed when not in use to prevent skin formation or changes in concentration.
