Quality Control

Our alkyd resin intermediates are manufactured under a stringent quality management system to ensure batch-to-batch consistency and performance. Key parameters such as acid value, viscosity, color, and solids content are rigorously tested against internal and customer specifications. Certificates of Analysis (COA) documenting these results are available for every shipment upon request, providing full traceability and quality assurance for your formulation process.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). This material is light-sensitive and easily oxidized; prolonged exposure to air, heat, or light should be avoided to maintain product integrity. Keep away from strong oxidizing agents and sources of ignition.
