Description

Stanniccitrate CAS NO 6493-69-2 is a specialized organotin compound, specifically a citrate salt of tin(IV). This chemical is valued for its unique properties as a stabilizer and catalyst in various high-performance polymer systems. It is primarily sought after by manufacturers in the plastics, coatings, and specialty chemical industries for applications requiring enhanced thermal stability and controlled reactivity.

Application

• PVC Stabilizer: Acts as a highly effective heat stabilizer in the production of rigid and flexible polyvinyl chloride (PVC) products, preventing degradation during processing.
• Polymer Catalyst: Serves as a catalyst or co-catalyst in polycondensation reactions, such as in the synthesis of certain polyesters and polyurethanes.
• Cross-linking Agent: Used in silicone rubber and other elastomer systems to facilitate cross-linking, improving mechanical properties and heat resistance.
• Antifouling Additive: Incorporated into marine paints and coatings for its biocidal properties, helping to prevent the growth of organisms on ship hulls.
• Glass & Ceramic Coatings: Functions as a precursor in sol-gel processes for depositing transparent, conductive, or protective tin oxide coatings on glass and ceramics.
• Wood Preservative: Used in formulations to protect timber from fungal decay and insect damage, often in combination with other biocides.

Quality Control

Our Stanniccitrate is produced under strict quality management protocols. Each batch undergoes comprehensive analytical testing to ensure it meets precise specifications for purity, metal content, and physical properties. A Certificate of Analysis (COA) detailing assay results, impurity profiles, and other critical parameters is provided with every shipment to guarantee traceability and compliance.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept sealed to prevent absorption of atmospheric moisture, which can affect product stability and performance.
