Quality Control

Our Reactive Red 152 is manufactured under a stringent quality management system. Every batch is tested to ensure it meets precise specifications for color strength, solubility, and reactive group content. A comprehensive Certificate of Analysis (COA) detailing purity, shade, and physical-chemical parameters is provided with each shipment to guarantee batch-to-batch consistency and performance reliability for your production.

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, the container must be kept tightly sealed after initial use to prevent moisture absorption, which can affect product performance.
