Quality Control

Every batch of our acrylic copolymer is manufactured under a strict quality management system. We ensure product consistency and performance through rigorous in-process and final batch testing against established internal specifications. Key parameters monitored include solids content, viscosity, pH, and glass transition temperature (Tg). A comprehensive Certificate of Analysis (COA) detailing all test results is provided with each shipment to guarantee traceability and compliance with your formulation requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). Keep away from heat sources and open flame. For long-term storage, an inert atmosphere (e.g., nitrogen blanket) is recommended to prevent skin formation or polymerization in the container headspace. Keep containers tightly sealed when not in use to prevent moisture absorption and solvent loss.
