Quality Control

Our production of this acrylic copolymer adheres to strict quality management systems to ensure batch-to-batch consistency and performance reliability. Every lot is characterized for critical parameters including monomer content, molecular weight distribution, viscosity, and glass transition temperature (Tg). Certificates of Analysis (COA) documenting full specifications are available upon request, supporting 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 heat sources and open flame. For long-term storage, an inert atmosphere (nitrogen blanket) is recommended to prevent polymer degradation.
