Quality Control

Our production of this polyester polyol copolymer adheres to stringent quality management systems to ensure batch-to-batch consistency and performance reliability. Key parameters such as hydroxyl value, acid value, viscosity, and color are rigorously tested against internal specifications. A comprehensive Certificate of Analysis (COA) detailing all test results 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 heat sources, open flames, and incompatible materials such as strong oxidizing agents. Under these conditions, the product is typically stable for 24 months from the date of manufacture. For long-term storage under optimal conditions, contact our technical service.
