Description

Di-n-Butyltin is a versatile organotin compound widely utilized as a key intermediate and catalyst in advanced chemical synthesis. Its primary commercial value lies in its role as a precursor for heat stabilizers and catalysts, which are critical for manufacturing high-performance polymers and coatings. This product is essential for industries focused on PVC stabilization, polyurethane production, and silicone curing, where precise catalytic activity and material stability are paramount.

Application

• PVC Heat Stabilizer Precursor: A key intermediate in the synthesis of organotin-based stabilizers for rigid and flexible PVC applications, including pipes, profiles, and films.
• Polyurethane Catalyst: Acts as a catalyst in the production of polyurethane foams and elastomers, promoting efficient reaction kinetics.
• Silicone Cross-linking Agent: Used in the curing and cross-linking processes for silicone rubbers and resins.
• Esterification & Transesterification Catalyst: Facilitates esterification and transesterification reactions in the synthesis of plasticizers, lubricants, and biodiesel.
• Intermediate for Biocides: Serves as a building block for certain organotin compounds with biocidal properties used in industrial preservatives.
• Glass Coating Precursor: Employed in the chemical vapor deposition (CVD) process for creating transparent conductive oxide coatings on glass.

Quality Control

Our Di-n-Butyltin is manufactured under stringent quality management systems to ensure batch-to-batch consistency and high purity. Quality is verified through a comprehensive suite of analytical techniques including Gas Chromatography (GC), Inductively Coupled Plasma (ICP) for metal content, and titration methods. A Certificate of Analysis (COA) detailing purity, assay, and impurity profiles is provided with each 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 a controlled room temperature (15-25°C). This material is easily oxidized; for long-term storage, it is recommended to keep the container under an inert atmosphere (e.g., nitrogen or argon). Keep away from strong bases and incompatible materials.
