Quality Control

Our production of this acrylic copolymer adheres to strict quality management protocols to ensure batch-to-batch consistency and performance reliability. Each lot is tested against key parameters including monomer content, epoxy value, viscosity, and solids content. Certificates of Analysis (COA) documenting these specifications 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, dry, and well-ventilated area at room temperature (15-25°C). Keep away from strong acids and organic solvents. For long-term storage, consider using under an inert atmosphere to prevent premature cross-linking.
