Quality Control

Our production of this alkyd resin intermediate 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 monitored. A comprehensive Certificate of Analysis (COA) detailing all relevant specifications is provided with each shipment to support your quality assurance processes.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area away from incompatible materials such as strong acids and organic solvents. Ideal storage temperature is between 15°C and 25°C (59°F and 77°F). Keep container tightly sealed when not in use to prevent skinning or moisture absorption.
