Quality Control

Our production of this advanced copolymer adheres to strict quality management systems to ensure batch-to-batch consistency and performance reliability. While specifications vary by grade, typical quality parameters monitored include viscosity, solids content, acid value, epoxy equivalent weight, and glass transition temperature (Tg). Certificates of Analysis (COA) documenting these and other relevant specifications are provided with every shipment.

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. Under recommended storage conditions, the product is typically stable for 24 months from the date of manufacture. Always check the specific technical data sheet for the grade in use.
