Quality Control

Our production of this alkyd resin adheres to strict quality management systems to ensure batch-to-batch consistency and performance reliability. Key parameters such as acid value, viscosity, solids content, and color are rigorously monitored. Certificates of Analysis (COA) documenting these specifications are available for every batch upon request, providing full traceability and compliance assurance for your manufacturing process.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area away from heat sources and open flame. Recommended storage temperature is between 15°C and 25°C (59°F and 77°F). Keep away from strong acids and oxidizing agents. Under these conditions, the product is typically stable for 24 months from the date of manufacture.
