Quality Control

Our Pr-Mdi is manufactured under stringent quality management systems to ensure batch-to-batch consistency and reliability. Each lot undergoes comprehensive analytical testing, including determination of NCO content, viscosity, and purity, to meet precise customer specifications. Certificates of Analysis (COA) documenting all critical parameters are available upon request, supporting compliance with industry and regulatory requirements.

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, containers must be kept tightly sealed under a dry inert atmosphere (e.g., nitrogen) to prevent moisture ingress and degradation. Isolate from strong bases, acids, alcohols, amines, and moisture.
