Quality Control

Our production of this polyurethane polyol adheres to strict quality management systems. Every batch undergoes comprehensive analytical testing to ensure consistent performance, including measurement of hydroxyl value (OHV), viscosity, isocyanate (NCO) content, and color. Certificates of Analysis (COA) detailing these specifications are provided and 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 / 59-77°F). This product is hygroscopic (moisture-sensitive); containers must be kept tightly sealed when not in use to prevent absorption of atmospheric moisture, which can affect product performance. Keep away from heat sources and open flame.
