Quality Control

Our Sunflower Oil, Trimethylolpropane, Isophthalic Acid Polymer is manufactured under a strict quality management system. Each batch undergoes comprehensive analytical testing to ensure consistent performance and meets agreed-upon specifications for parameters such as acid value, hydroxyl value, viscosity, and color. Certificates of Analysis (COA) documenting these results are available upon request to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area away from strong acids and organic solvents. 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 skin formation.
