Quality Control

Our acrylic copolymer is manufactured under a strict quality management system to ensure batch-to-batch consistency and performance reliability. Each lot is tested against comprehensive specifications covering molecular weight distribution, solids content, viscosity, glass transition temperature (Tg), and acid value. Certificates of Analysis (COA) detailing these parameters are provided with every shipment. Our production adheres to relevant ISO 9001 standards, and we support our global clients with documentation for REACH and other regional regulatory compliance.

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). Do not freeze. Keep away from heat sources and open flame. Under these conditions, the product is typically stable for 24 months from the date of manufacture. Always check the specific label or technical data sheet for the recommended shelf life of your purchased grade.
