Quality Control

Our production of this acrylic copolymer adheres to strict quality management systems to ensure batch-to-batch consistency and performance reliability. Key parameters such as solids content, viscosity, glass transition temperature (Tg), and mechanical properties are rigorously tested. Certificates of Analysis (COA) documenting these specifications are provided with every shipment. We support compliance with relevant global regulatory frameworks for industrial chemicals.

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, strong bases, and open flames. Ensure containers are kept tightly sealed when not in use to prevent skinning or changes in viscosity.
