Quality Control

Our production of this alkyd resin intermediate adheres to strict quality management systems to ensure batch-to-batch consistency and performance reliability. Key parameters such as acid value, viscosity, color, and solids content are rigorously monitored. A comprehensive Certificate of Analysis (COA) detailing all specifications is provided with each shipment to support your quality assurance protocols.

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 strong alkalis and incompatible organic solvents. For long-term storage, ensure containers are sealed under an inert atmosphere to prevent skin formation or oxidative degradation.
