Description

Luxol Fast Blue Arn is a specialized solvent dye belonging to the class of triphenylmethane dyes, identified by CAS No. 12226-74-3. It is valued for its intense blue coloration and excellent solubility in a range of non-polar to moderately polar organic solvents. This product is essential for industrial applications requiring durable, transparent colorants. Key industries that utilize this dye include plastics, inks, and coatings, where it provides consistent tinting strength and stability.

Application

• Plastics Coloring: Used as a colorant for polystyrene, acrylics, and other engineering plastics to achieve vibrant blue hues.
• Ink Formulation: A key component in solvent-based printing inks for packaging and specialty printing due to its clarity and lightfastness.
• Coatings and Paints: Imparts color to lacquers, wood stains, and automotive refinish coatings where solvent compatibility is critical.
• Fuel and Oil Marking: Employed as a dye for industrial fuels, lubricants, and greases for identification purposes.
• Wax and Polishes: Provides coloration in candle wax, shoe polishes, and floor care products.
• Biological Staining (Histology): Used in specific histological staining protocols for nervous tissue, often in combination with other dyes.
