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 acid value, hydroxyl value, viscosity, glass transition temperature (Tg), and color are rigorously monitored. Certificates of Analysis (COA) detailing these specifications are provided with each 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, well-ventilated area at room temperature (15-25°C). Keep away from strong acids and organic solvents. The material should be kept under dry conditions to prevent moisture absorption, which may affect its properties.
