Quality Control

Our production of this polymeric ester adheres to strict quality management systems. Every batch undergoes rigorous analytical testing to ensure consistent performance, including assessment of molecular weight distribution, acid value, hydroxyl value, and viscosity. Certificates of Analysis (COA) detailing all critical specifications are provided and 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 at temperatures between 15-25°C (59-77°F). This product is easily oxidized; prolonged storage under an inert atmosphere (e.g., nitrogen) is recommended for optimal long-term stability. Keep away from strong alkalis and incompatible organic solvents.
