Quality Control

Our production of this polyurethane polymer adheres to strict quality management systems. Each batch is characterized for critical parameters including NCO content, viscosity, solids content, and color to ensure consistency and performance. Certificates of Analysis (COA) documenting these specifications are available upon request to support your quality assurance and regulatory 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). Keep away from heat, sparks, and open flame. Moisture-sensitive; keep container tightly sealed to prevent reaction with atmospheric humidity. Separate from strong acids, bases, and oxidizing agents.
