Quality Control

Our production of 2,5-Furandione, Dihydro-, Polymer With 1,2-Ethanediol, 1,1-Methylenebis4-Isocyanatobenzene And 2,2-Oxybisethanol adheres to stringent quality management protocols. Every batch undergoes rigorous analytical testing to ensure consistent composition, functionality, and performance. Certificates of Analysis (COA) detailing key parameters such as NCO content, viscosity, and solids content are available upon request to support your quality assurance and regulatory compliance needs.

Storage

Preserve in a tightly closed, moisture-proof container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (typically 15-25°C). Keep away from heat, open flames, and sources of ignition. Due to the reactive isocyanate groups, protect from moisture to prevent premature curing or gelation. Shelf life is optimal when stored under these conditions.
