Quality Control

Our acrylic copolymer is manufactured under a stringent quality management system. Each batch undergoes rigorous analytical testing to ensure consistent performance, including measurement of solid content, viscosity, pH, and glass transition temperature (Tg). Certificates of Analysis (COA) detailing batch-specific results 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, and well-ventilated area at temperatures between 15°C and 25°C (59°F and 77°F). Keep away from strong acids and organic solvents. For long-term storage, ensure containers are sealed to prevent skin formation or changes in viscosity.
