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 specification sheet, with key parameters including monomer content, molecular weight distribution, solids content, viscosity, and glass transition temperature (Tg). A Certificate of Analysis (COA) documenting these results 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 room temperature (15-25°C). Keep away from heat sources and open flame. Under these conditions, the product has a typical shelf life of 12-24 months from the date of manufacture. Always check the specific label or technical data sheet for the recommended shelf life of your purchased grade.
