Quality Control

Our production of this specialty copolymer adheres to strict quality management systems to ensure batch-to-batch consistency and performance reliability. Key parameters such as viscosity, hydroxyl value, acid value, and glass transition temperature (Tg) are rigorously monitored. 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 a controlled room temperature (typically 15-25°C). This product is hygroscopic (moisture-sensitive). Keep the container tightly sealed when not in use to prevent moisture absorption, which can affect product performance. Keep away from heat sources and open flame.
