Quality Control

Our production of this polymer adheres to strict quality management protocols to ensure batch-to-batch consistency and performance reliability. Key parameters such as NCO content (if applicable), viscosity, solids content, acid value, and hydroxyl value are rigorously monitored. A comprehensive Certificate of Analysis (COA) detailing the specific specifications for your ordered grade is provided with every shipment to support your quality assurance and regulatory compliance needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C / 59-77°F). This material is hygroscopic (moisture-sensitive); containers must be kept sealed to prevent absorption of atmospheric moisture, which can affect product performance. Keep away from heat, sparks, and open flame.
