Quality Control

Our Bis-(4-Aminophenyl)-Methane-Trimellitic Anhydride Copolymer is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing to ensure consistent performance, including assessment of inherent viscosity, amine end-group content, and residual solvent levels. Certificates of Analysis (COA) documenting key specifications are available upon request 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). This material is hygroscopic (moisture-sensitive); containers must be kept sealed to prevent absorption of atmospheric moisture, which can affect product performance.
