Quality Control

Our production of Linseed/Isophthalic-Terephthalic/Pentaerythritol/Glycerol adheres to stringent quality management protocols to ensure batch-to-batch consistency and performance reliability. Each lot undergoes comprehensive analytical testing, including viscosity, acid value, color, and solids content determination. Certificates of Analysis (COA) documenting all critical parameters 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 away from heat sources and incompatible materials such as strong acids and organic solvents. Due to its nature of being easily oxidized, it is recommended to store under an inert atmosphere (e.g., nitrogen blanket) for long-term storage to maintain optimal quality. Recommended storage temperature is between 15°C and 25°C (59°F and 77°F).
