Quality Control

Our products undergo rigorous quality testing to ensure compliance with industry standards and batch-to-batch consistency. Quality parameters are monitored against stringent internal specifications, with a focus on key properties such as acid value, hydroxyl value, viscosity, and thermal stability. Certificates of Analysis (COA) detailing these specifications are available upon request to support your quality assurance and regulatory 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). Keep away from strong acids and organic solvents. Ensure the container is kept tightly sealed to prevent moisture absorption and contamination.
