Quality Control

Our Solvent Red 168 is manufactured under a stringent quality management system to ensure it meets the precise requirements of industrial applications. Each batch is tested against key parameters including color strength, hue, solubility, and thermal stability. A Certificate of Analysis (COA) documenting purity, physical properties, and performance characteristics is available for every shipment to guarantee traceability and compliance.

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.
