Quality Control

Our products undergo rigorous quality testing to ensure compliance with industry standards. Certificates of Analysis (COA) are available upon request, detailing key parameters such as NCO content, viscosity, and color. We adhere to a cGMP-compliant quality management system to guarantee batch-to-batch consistency and reliability for your formulations.

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 easily oxidized and should be stored under an inert atmosphere (e.g., nitrogen blanket) after opening to prevent degradation. Keep away from heat, sparks, and open flame.
