Quality Control

Our production of this acrylic copolymer adheres to strict quality management systems, ensuring batch-to-batch consistency and performance reliability. Every lot is tested against a comprehensive specification sheet, with key parameters including solids content, viscosity, pH, and glass transition temperature (Tg) verified. Certificates of Analysis (COA) documenting all test results 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, well-ventilated area at temperatures between 15°C and 25°C (59°F and 77°F). Avoid exposure to extreme heat or freezing conditions to maintain product stability and prevent phase separation or viscosity changes. Keep away from strong oxidizing agents.
