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 characterized for critical parameters including solid content, viscosity, acid value, glass transition temperature (Tg), and molecular weight distribution. A comprehensive Certificate of Analysis (COA) detailing these specifications is 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, and well-ventilated area at temperatures between 15°C and 25°C (59°F and 77°F). Avoid freezing and prolonged exposure to elevated temperatures to prevent changes in viscosity or polymer stability. Keep away from strong oxidizing agents and incompatible materials.
