Quality Control

Our n-(Benzothiazol-2-Ylthio)-n-Cyclohexylbenzothiazole-2-Sulphenamide is manufactured under a strict quality management system. Every batch undergoes rigorous analytical testing, including assay, melting point determination, and ash content analysis, to ensure it meets the high-purity standards required for industrial rubber processing. A Certificate of Analysis (COA) detailing all specifications is provided with each shipment to guarantee traceability and consistent performance.

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). Keep away from heat sources, open flames, and incompatible materials such as strong oxidizing agents. The product has low hygroscopicity but should be protected from prolonged exposure to high humidity to prevent caking.
