Quality Control

Our Linseed Oil, Polymer With Pentaerythritol, Rosin And Tung Oil is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing to ensure consistent performance in viscosity, acid value, color, and solids content. Certificates of Analysis (COA) documenting these key parameters are available upon request to support your quality assurance and formulation processes.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated area away from heat sources and open flames. Due to its easily oxidized nature, it is recommended to store under an inert atmosphere (e.g., nitrogen blanket) for long-term storage to prevent skinning and gelation. Ideal storage temperature is between 15°C and 25°C (59°F and 77°F). Keep away from strong oxidizing agents.
