Quality Control

Every batch of Astrazon Pink Fg is manufactured and tested under a strict quality management system to ensure it meets the high standards required for industrial dyeing processes. Our quality control includes verification of color strength, shade, solubility, and purity against established internal specifications. A comprehensive Certificate of Analysis (COA) detailing assay, impurity profile, and physical properties is provided with each shipment to guarantee traceability and consistency.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after each use to prevent absorption of atmospheric moisture, which can affect performance.
