Quality Control

Our production of this acrylic copolymer adheres to strict quality management systems to ensure batch-to-batch consistency and performance reliability. Each lot is characterized for critical parameters including monomeric composition, molecular weight distribution, viscosity, solids content, and glass transition temperature (Tg). Certificates of Analysis (COA) detailing these specifications are provided with every shipment. We support compliance with relevant global regulatory frameworks, including REACH.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (typically 15-25°C). Keep away from heat sources and open flame. For long-term storage, ensure containers are sealed to prevent moisture absorption or solvent loss, which may alter product properties.
