Quality Control

Our Polymerized Tung Oil is produced under strict quality management protocols. Each batch is tested against key parameters including viscosity, acid value, color, and drying time to ensure consistent performance for industrial applications. A Certificate of Analysis (COA) documenting these results is provided with every shipment to guarantee traceability and compliance with your specifications.

Storage

Preserve in a tightly closed container, protected from light. This product is easily oxidized and should be stored under an inert atmosphere (e.g., nitrogen blanket) when in partially filled containers to prevent skinning and viscosity increase. Store in a cool, dry, well-ventilated area away from heat sources and open flame. Recommended storage temperature is 15-25°C (59-77°F).
