Description

Tin Dilinoleate is an organotin compound derived from linoleic acid, serving as a versatile catalyst and stabilizer in polymer chemistry. Its primary value lies in its effectiveness as a heat stabilizer for polyvinyl chloride (PVC) and as a catalyst for esterification and transesterification reactions. This product is essential for manufacturers in the plastics, coatings, and lubricant industries seeking to enhance material performance and processing efficiency.

Application

• PVC Heat Stabilizer: Used to prevent thermal degradation during the processing of rigid and flexible PVC products, including pipes, profiles, and cables.
• Esterification Catalyst: Catalyzes the production of esters for synthetic lubricants, plasticizers, and biodiesel.
• Polyurethane Catalyst: Acts as a catalyst in the formulation of polyurethane foams and elastomers.
• Lubricant Additive: Functions as a friction modifier and anti-wear agent in advanced lubricating greases and oils.
• Silicone Cross-linking Agent: Employed in the curing of silicone polymers for sealants and rubbers.
• Paint and Coating Additive: Improves the drying properties and film formation in alkyd resins and other coating systems.

Quality Control

Our Tin Dilinoleate is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing to ensure it meets precise specifications for purity, metal content, and performance characteristics. A comprehensive Certificate of Analysis (COA) detailing assay, impurity profile, and physical properties 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, 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 efficacy. Keep away from strong acids and oxidizing agents.
