Description

Tin Di(Octanolate) is an organotin compound widely used as a catalyst and stabilizer in various industrial polymerization processes. Its primary value lies in its effectiveness as a polycondensation catalyst for producing high-performance polyesters and polyurethanes. This product is essential for manufacturers in the plastics, coatings, and specialty polymer industries seeking to control reaction kinetics and final product properties.

Application

• Polyester Production Catalyst: A key catalyst for the polycondensation reaction in manufacturing saturated and unsaturated polyesters for resins, fibers, and films.
• Polyurethane Catalyst: Used as a catalyst in the production of polyurethane foams, elastomers, and coatings, influencing cure rates and final material characteristics.
• Silicone Cross-linking Agent: Acts as a catalyst in the curing (cross-linking) of silicone polymers, particularly in room-temperature vulcanizing (RTV) systems.
• Esterification & Transesterification: Facilitates esterification and transesterification reactions in organic synthesis and the production of plasticizers and lubricants.
• Stabilizer for PVC: Functions as a heat stabilizer in certain polyvinyl chloride (PVC) formulations to prevent degradation during processing.
• Specialty Polymer Additive: Employed in the synthesis of specialized polymers where precise catalytic activity is required for controlled molecular weight and architecture.

Quality Control

Our Tin Di(Octanolate) is produced under strict quality management protocols to ensure batch-to-batch consistency and performance reliability. Each lot undergoes comprehensive analysis, including assay, identification, and impurity profiling. A Certificate of Analysis (COA) detailing all test results is provided with every shipment to support your quality assurance and regulatory compliance needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). This product is hygroscopic (moisture-sensitive). Keep the container tightly sealed when not in use to minimize exposure to atmospheric moisture, which can affect catalytic activity.
