Quality Control

Our acrylic copolymer is manufactured under a stringent quality management system to ensure batch-to-batch consistency and performance reliability. Each lot is tested against critical parameters including solid content, viscosity, glass transition temperature (Tg), and residual monomer levels. Certificates of Analysis (COA) documenting full specifications are available upon request to support your quality assurance and regulatory compliance needs.

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 heat sources and open flame. For long-term storage, ensure containers are sealed to prevent moisture absorption or skin formation.
