Quality Control

Our Disperse Blue 109 is manufactured under a strict quality management system to ensure batch-to-batch consistency and compliance with industry standards. Each lot is tested for critical parameters including color strength, shade, dispersion stability, and particle size distribution. A comprehensive Certificate of Analysis (COA) detailing purity, physical properties, and performance characteristics is provided with every shipment to guarantee it meets your specific application 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). Keep away from heat sources and incompatible materials. Due to its light-sensitive nature, prolonged exposure to direct light should be avoided to maintain product integrity.
