Quality Control

Our production of this specialty polymer adheres to strict quality management protocols to ensure batch-to-batch consistency and performance reliability. Key parameters such as viscosity, hydroxyl value, isocyanate content, and molecular weight distribution are rigorously monitored. Certificates of Analysis (COA) detailing specific lot specifications are available upon request to support your quality assurance and regulatory compliance needs.

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). This material is moisture-sensitive; keep the container tightly sealed to prevent absorption of atmospheric moisture, which can affect product performance.
