Quality Control

Our production of this metallized dye complex adheres to strict quality management protocols. Every batch undergoes comprehensive analysis to ensure consistency in color strength, metal content, and impurity profile. Certificates of Analysis (COA) detailing specifications such as purity, ash content, and solubility 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). Keep away from strong oxidizing agents. The product is hygroscopic (moisture-sensitive); ensure containers are sealed after each use to prevent moisture absorption.
