Quality Control

Our production of this acrylic copolymer adheres to strict quality management systems, ensuring batch-to-batch consistency for reliable formulation performance. While specific grades may be tailored, our standard quality control includes testing for key parameters such as solids content, viscosity, glass transition temperature (Tg), and amine value. Certificates of Analysis (COA) documenting these specifications are provided with every shipment. We can also support compliance with relevant regulatory frameworks such as REACH and FDA for appropriate applications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (typically 15-25°C). Keep away from sources of heat and ignition. For long-term storage, consider under an inert atmosphere to prevent oxidation. Keep container tightly sealed when not in use to prevent moisture absorption and skin formation.
