Quality Control

Our production of this advanced polymer adheres to strict quality management systems. Every batch undergoes comprehensive analytical testing to ensure consistency in NCO content, viscosity, solids content, and color. A Certificate of Analysis (COA) detailing all relevant specifications is provided with each shipment to guarantee it meets your formulation requirements.

Storage

Preserve in a tightly closed, moisture-proof container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). This product is hygroscopic (moisture-sensitive). Prolonged exposure to atmospheric moisture will compromise product integrity. Keep away from heat sources and open flame.
