Quality Control

Our production of this 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, and glass transition temperature (Tg). Certificates of Analysis (COA) documenting these specifications are provided with every shipment. We support compliance with global regulatory frameworks such as 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 strong acids and organic solvents. The material is light-sensitive; prolonged exposure to direct light should be avoided to maintain product integrity.
