Quality Control

Our Synacril Black An is produced under a stringent quality management system to ensure batch-to-batch consistency and performance. Each lot is tested against rigorous internal specifications for critical parameters such as color strength, solubility, and impurity profile. 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). This material is hygroscopic (moisture-sensitive); keep the container tightly sealed when not in use to prevent absorption of atmospheric moisture, which can affect performance.
