Quality Control

Our production of this advanced copolymer adheres to stringent quality management systems to ensure batch-to-batch consistency and performance reliability. Each lot is characterized for critical parameters including monomer content, epoxy value, molecular weight distribution, viscosity, and glass transition temperature (Tg). Certificates of Analysis (COA) documenting these specifications are provided with every shipment. We support compliance with global regulatory frameworks such as REACH.

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 is typically stable for 24 months from the date of manufacture. Always refer to the specific Material Safety Data Sheet (MSDS) for detailed handling and storage instructions.
