Quality Control

Our production of this advanced acrylic copolymer adheres to strict quality management systems, ensuring batch-to-batch consistency and performance reliability. Each lot is characterized for critical parameters including monomer content, molecular weight distribution, epoxy value (for glycidyl functionality), viscosity, and solids content. Certificates of Analysis (COA) documenting these specifications are provided with every shipment 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 under warm conditions, consult the technical data sheet for specific recommendations.
