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 molecular weight distribution, monomer residue, viscosity, and glass transition temperature (Tg) are rigorously monitored. A comprehensive Certificate of Analysis (COA) detailing all specifications is provided with each shipment to support your quality assurance processes.

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. For long-term storage, ensure containers are sealed to prevent moisture absorption and skin formation.
