Quality Control

Our production of this acrylic copolymer adheres to strict quality management systems. Each batch is characterized for critical parameters including monomer residue, molecular weight distribution, solids content, viscosity, and acid value to ensure batch-to-batch consistency. Certificates of Analysis (COA) documenting these specifications are provided with every shipment. We support compliance with relevant global regulatory frameworks.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). Keep away from heat sources and open flame. For long-term storage, consider under an inert atmosphere to prevent oxidation or moisture uptake, which may affect polymer properties.
