Quality Control

Our production of this advanced copolymer adheres to strict quality management systems. Each batch undergoes comprehensive analysis to ensure consistency in key parameters such as molecular weight distribution, glass transition temperature (Tg), acid value, and hydroxyl value. Certificates of Analysis (COA) detailing these specifications are provided with every shipment. We support compliance with relevant global regulatory frameworks, including REACH.

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 flame. This material is hygroscopic (moisture-sensitive); ensure containers are sealed after use to prevent moisture absorption which may affect processing properties.
