Description

Solvent Blue 74 is a high-performance, oil-soluble anthraquinone dye known for its excellent solubility in non-polar organic solvents and its vibrant, stable blue coloration. This product is essential for industries requiring consistent, high-quality tinting and coloration of hydrophobic materials. It is primarily used by manufacturers in the plastics, inks, coatings, and specialty chemical sectors for precise color matching and product differentiation.

Application

• Plastics Coloring: Used as a masterbatch or direct colorant for a wide range of polymers, including polyolefins (PP, PE), polystyrene, and ABS, providing excellent dispersion and heat stability.
• Ink Formulation: A key pigment for solvent-based printing inks, including flexographic and gravure inks, offering strong tinctorial strength and good lightfastness.
• Industrial Coatings & Paints: Imparts durable blue shades to industrial finishes, automotive refinish paints, and wood stains where solvent compatibility is required.
• Waxes & Polishes: Employed to color paraffin waxes, shoe polishes, and other wax-based products for consistent batch-to-batch appearance.
• Specialty Chemical Intermediates: Serves as a colorant in the production of specialty chemicals, lubricants, and cleaning agents.
• Fuel & Oil Marking: Used in trace amounts for the visual identification and marking of fuels and industrial oils.
