Quality Control

Our Sulfur Green 36 is manufactured under a strict quality management system to ensure batch-to-batch consistency and performance. Quality parameters including color strength, hue, particle size distribution, and chemical purity are rigorously tested against established internal specifications. A Certificate of Analysis (COA) detailing these results 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 area at room temperature (15-25°C). Due to its hygroscopic nature, the container must be kept tightly sealed after opening to prevent moisture absorption, which can affect product performance.
