Quality Control

Our production of this advanced polymer resin adheres to strict quality management systems, ensuring batch-to-batch consistency and performance reliability. Each lot is characterized for critical parameters including solid content, viscosity, acid value, hydroxyl value, and color. A comprehensive Certificate of Analysis (COA) detailing these specifications is provided with every 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 temperatures between 15°C and 25°C (59°F and 77°F). Keep away from heat sources and open flame. Under these conditions, the product is typically stable for 24 months from the date of manufacture. For prolonged storage, monitor viscosity and appearance periodically.
