Quality Control

Our production of this advanced polymer adheres to strict quality management systems, ensuring batch-to-batch consistency for critical performance parameters like NCO content, viscosity, and hydroxyl value. Quality is verified through analytical techniques including titration, gel permeation chromatography (GPC), and FT-IR spectroscopy. A Certificate of Analysis (COA) detailing key specifications is provided with each shipment to support your quality assurance protocols.

Storage

Preserve in a tightly closed, moisture-proof container, protected from light. Store in a cool, dry, and well-ventilated area at temperatures recommended for polyurethane prepolymers (typically between 15°C and 25°C). Keep away from heat, sparks, and open flame. Due to its reactivity with moisture and strong bases/organic solvents as indicated, ensure containers are sealed under a dry inert atmosphere (e.g., nitrogen) after opening to prevent premature curing or gelation.
