Description

Dibutyltin Diacetate is a versatile organotin compound widely recognized as a highly effective catalyst and stabilizer in industrial polymer chemistry. Its primary value lies in accelerating key chemical reactions, such as polyurethane formation and esterification, while also preventing degradation in various polymer systems. This makes it an essential material for manufacturers in the plastics, coatings, and adhesive industries seeking to optimize production efficiency and product performance.

Application

• Polyurethane Catalyst: A key catalyst for the production of flexible and rigid polyurethane foams, elastomers, and coatings.
• PVC Stabilizer: Acts as a heat stabilizer in polyvinyl chloride (PVC) processing to prevent thermal degradation during extrusion and molding.
• Esterification & Transesterification Catalyst: Used to catalyze the synthesis of esters, plasticizers, and biodiesel.
• Silicone Curing Agent: Facilitates the room-temperature vulcanization (RTV) of silicone rubbers and sealants.
• Adhesive & Sealant Formulations: Enhances cure rates and final properties in various industrial adhesive systems.
• Cross-linking Agent: Employed in the production of specialty polymers and resins requiring controlled cross-linking.

Quality Control

Our Dibutyltin Diacetate is manufactured under strict quality management protocols to ensure batch-to-batch consistency and high purity. The product is tested against rigorous in-house specifications, which typically include assay, tin content, and impurity profile analysis. A Certificate of Analysis (COA) detailing the results for each production lot is available upon request to support your quality assurance and regulatory needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area away from incompatible materials such as strong bases and oxidizing agents. Recommended storage temperature is between 15°C and 25°C. The container must be kept tightly sealed due to sensitivity to moisture.
