Quality Control

Our production of this acrylic copolymer adheres to strict quality management systems. Every batch is tested against a comprehensive set of parameters to ensure consistency and performance. Certificates of Analysis (COA) detailing key specifications such as solids content, viscosity, acid value, and glass transition temperature (Tg) are available upon request to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (typically 15-25°C). Keep away from heat sources and open flames. For long-term storage, ensure containers are properly sealed to prevent skin formation or changes in viscosity.
