Quality Control

Our products undergo rigorous quality testing to ensure compliance with industry standards. Production follows strict protocols to guarantee batch-to-batch consistency in properties such as NCO content, viscosity, and hydroxyl value. Certificates of Analysis (COA) detailing key specifications are available upon request to support your quality assurance processes.

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). Due to its hygroscopic (moisture-sensitive) nature, containers must be kept sealed to prevent exposure to atmospheric moisture, which can compromise product integrity. Keep away from heat, sparks, and open flame.
