Quality Control

Our Reactive Green 16 is manufactured under a strict quality management system. Every batch undergoes comprehensive analytical testing to ensure it meets precise specifications for color strength, hue, and reactive group content. A Certificate of Analysis (COA) detailing purity, physical properties, and performance metrics is provided with each shipment, ensuring traceability and consistency for our global B2B customers.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated place at room temperature (15-25°C). This material is hygroscopic (moisture-sensitive); ensure the container is kept tightly sealed to prevent absorption of atmospheric moisture which can affect performance.
