Quality Control

Our Hexanedioic Acid, Polymer With 1,3-Isobenzofurandione And 1,2-Propanediol, 2-Ethylhexyl Ester is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing to ensure consistent performance, including assessment of acid value, hydroxyl value, viscosity, color, and refractive index. Certificates of Analysis (COA) documenting full specifications are available upon request to support your quality assurance and regulatory compliance needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C/59-77°F). Keep away from strong acids and incompatible organic solvents. The container should be kept tightly sealed when not in use to prevent moisture absorption and maintain product integrity.
