Quality Control

Our Neofos 2 is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing to ensure consistent purity, performance, and compliance with relevant industry specifications for flame retardant applications. Certificates of Analysis (COA) documenting key parameters such as assay, acidity, and refractive index 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). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after opening to prevent degradation from atmospheric moisture.
