Quality Control

Our production of 2,2-Bis(4-isocyanatophenyl)hexafluoropropane adheres to stringent quality management protocols. Every batch undergoes comprehensive analytical testing, including assay, isocyanate content, and impurity profiling, to ensure consistency and high purity. Certificates of Analysis (COA) documenting all critical parameters are available upon request to support your quality assurance and regulatory needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at temperatures between 2°C and 8°C (refrigerated) or as specified on the label. This material is hygroscopic (moisture-sensitive) and highly volatile. Containers must be kept tightly sealed under a dry inert atmosphere (e.g., nitrogen or argon) to prevent moisture ingress and polymerization. Keep away from strong bases and organic solvents.
