Description

Oil Blue N is a synthetic anthraquinone-based dye known for its excellent oil solubility and vibrant blue color. This product is essential for providing clear, stable coloration in non-aqueous systems where traditional water-soluble dyes are ineffective. It is primarily used by manufacturers in the plastics, petroleum, and specialty chemical industries for product identification, quality control, and aesthetic enhancement.

Application

• Coloration of lubricating oils, greases, and fuels for identification and leak detection.
• Masterbatch and compound coloring for olefin-based plastics (e.g., polyethylene, polypropylene).
• Staining and marking of waxes, paraffins, and other hydrocarbon-based materials.
• As a colorant in specialty inks and coatings for non-polar solvent systems.
• Used in laboratory settings as a microscopic stain or tracer dye in organic phases.
• Color coding of industrial chemicals and solvents for safety and process management.
