Quality Control

Our production of Copper Phthalocyanine Sulfonic Acid Derivatives adheres to stringent quality protocols to ensure batch-to-batch consistency and performance. Each lot undergoes comprehensive analysis, including purity assay, shade strength evaluation, and solubility testing. A Certificate of Analysis (COA) detailing all relevant specifications is provided with every shipment to guarantee compliance with your technical requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at 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 product performance.
