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 solid content, viscosity, glass transition temperature (Tg), and mechanical properties are rigorously tested. Certificates of Analysis (COA) documenting full specifications are available for every shipment upon request, supporting 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). Avoid freezing and prolonged exposure to high temperatures to prevent changes in viscosity or polymer stability. Keep away from open flames and sources of ignition.
