Quality Control

Our production of this advanced polyimide precursor adheres to rigorous quality control protocols to ensure batch-to-batch consistency and performance. Quality is verified through analytical techniques including FT-IR, GPC, and thermal analysis. A Certificate of Analysis (COA) detailing specific lot parameters is provided with every shipment to support your quality assurance and regulatory needs.

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 tightly sealed to exclude moisture and prevent degradation of the reactive oligomer.
