Quality Control

Our production of this modified alkyd resin adheres to strict quality management protocols to ensure batch-to-batch consistency and performance reliability. Key parameters such as acid value, viscosity, solids content, and color are rigorously tested. Certificates of Analysis (COA) documenting all relevant 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, and well-ventilated area at room temperature (15-25°C/59-77°F). Keep away from heat, sparks, and open flame. This product is sensitive to strong acids and organic solvents and is easily oxidized; it is recommended to store under an inert atmosphere or with a nitrogen blanket for long-term storage to prevent skinning and gelation.
