Quality Control

Our production of this advanced copolymer adheres to strict quality management systems to ensure batch-to-batch consistency and performance reliability. Each lot is characterized for critical parameters including acid value, hydroxyl value, viscosity, glass transition temperature (Tg), and color. Certificates of Analysis (COA) detailing these specifications are provided with every shipment. We support compliance with global regulatory frameworks, including REACH, and can tailor specifications to meet specific customer or application standards.

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). Keep away from heat sources and open flames. Under these conditions, the product is stable for extended periods. For long-term storage, consider an inert atmosphere to prevent moisture absorption and oxidative degradation.
