Quality Control

Our production of this advanced polymer intermediate adheres to strict quality management systems. Each batch undergoes rigorous analytical testing, including determination of NCO (isocyanate) content, viscosity, moisture content, and residual monomer levels, to ensure consistency and performance. Certificates of Analysis (COA) documenting all critical specifications are provided with every shipment. We support compliance with relevant industry standards and can tailor specifications to meet specific customer requirements.

Storage

Preserve in a tightly closed, moisture-proof container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (typically 15-25°C). This product is hygroscopic (moisture-sensitive) and must be protected from atmospheric humidity to prevent degradation. Keep away from heat, open flames, and incompatible materials such as alcohols, amines, and water.
