Quality Control

Our production of this acrylic copolymer adheres to strict quality management protocols to ensure batch-to-batch consistency and performance reliability. Key parameters such as solid content, viscosity, molecular weight distribution, and acid value are rigorously monitored. Certificates of Analysis (COA) documenting these specifications are available for every batch to support your quality assurance and regulatory compliance needs.

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 heat sources and open flames. For long-term storage, ensure the container is properly sealed to prevent skin formation or changes in viscosity.
