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, acid value, and glass transition temperature (Tg) are rigorously monitored. Certificates of Analysis (COA) detailing all relevant specifications are provided with each shipment to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). Keep away from heat sources and open flame. For long-term storage, ensure containers are sealed to prevent skin formation or changes in viscosity.
