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 tested against a comprehensive set of physical, chemical, and application-specific parameters. Certificates of Analysis (COA) detailing assay, viscosity, solids content, acid value, and other critical specifications 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, well-ventilated area at temperatures between 15°C and 25°C (59°F and 77°F). Keep away from heat sources and open flame. For long-term storage, ensure containers are kept tightly sealed to prevent skinning or changes in viscosity due to solvent evaporation or moisture absorption.
