Quality Control

Our production of this acrylic copolymer adheres to strict quality management systems to ensure batch-to-batch consistency and performance reliability. Each lot is characterized for critical parameters including molecular weight distribution, glass transition temperature (Tg), solids content, and viscosity. Certificates of Analysis (COA) detailing these specifications are provided with every shipment to support your quality assurance protocols.

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 containers are sealed to prevent moisture absorption or solvent evaporation, which may alter product properties.
