Description

Tributyltin Benzoate is an organotin compound that functions as a highly effective stabilizer and catalyst in various industrial polymerization processes. Its primary commercial value lies in its ability to prevent degradation and control reaction kinetics, ensuring consistent product quality and performance. This chemical is essential for manufacturers in the plastics, coatings, and specialty chemical sectors seeking reliable additives for PVC stabilization and polyurethane formulations.

Application

• PVC Stabilizer: Acts as a highly effective heat stabilizer in the production of rigid and flexible polyvinyl chloride (PVC) products, preventing decomposition during processing.
• Polyurethane Catalyst: Serves as a catalyst in the production of polyurethane foams and elastomers, controlling the reaction between isocyanates and polyols.
• Silicone Cross-linking Agent: Used as a catalyst in condensation-cure silicone rubber systems to promote cross-linking and cure.
• Antifouling Agent Intermediate: Functions as a key intermediate in the synthesis of tributyltin-based antifouling paints for marine coatings (subject to regional regulations).
• Esterification & Transesterification Catalyst: Catalyzes esterification and transesterification reactions in the production of plasticizers, lubricants, and biodiesel.
• Wood Preservative: Used in formulations for protecting wood against fungal decay and insect damage.

Quality Control

Our Tributyltin Benzoate is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing, including assay by titration, identification via FT-IR, and quantification of key impurities, to ensure it meets precise customer specifications and industry standards. A Certificate of Analysis (COA) detailing purity, physical properties, and test results is provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). This material is easily oxidized and should be kept under an inert atmosphere (e.g., nitrogen) for long-term storage to maintain stability. Keep away from strong oxidizing agents, strong acids, and strong bases.
