Quality Control

Our acrylic copolymer is manufactured under a strict quality management system. Each batch undergoes rigorous testing for critical parameters including solids content, viscosity, glass transition temperature (Tg), and acid value to ensure consistent performance and batch-to-batch uniformity. Certificates of Analysis (COA) detailing these specifications are available upon request 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 moisture absorption or skin formation.
