Quality Control

Our O,O'-Bis(2-Methylbutyl) Hydrogen Dithiophosphate, Zinc Salt is manufactured under a strict quality management system. Each batch is analyzed to ensure consistent performance as a lubricant additive, with key parameters including zinc content, phosphorus content, sulfur content, and viscosity. A Certificate of Analysis (COA) detailing these specifications is provided with every shipment to guarantee it meets your formulation requirements.

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 (59°F and 77°F). Keep container tightly sealed when not in use to prevent moisture absorption and contamination.
