Quality Control

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

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/59-77°F). This product is hygroscopic (moisture-sensitive); containers must be kept tightly sealed to prevent moisture absorption, which can affect product performance.
