Description

Solvent Blue 136 is a high-performance, oil-soluble anthraquinone dye renowned for its excellent solubility and stability in non-polar organic media. This compound is engineered to deliver intense, durable blue coloration for a wide range of industrial applications where traditional pigments may fail. It is a critical component for manufacturers in the plastics, specialty inks, and coatings sectors seeking reliable and consistent color performance.

Application

• Plastics Coloring: Primary application for coloring a variety of polymers, including polystyrene, ABS, polycarbonate, and polyolefins, offering excellent heat stability and dispersion.
• Specialty Inks: Used in solvent-based printing inks, including flexographic and gravure inks, providing vibrant color and good printability.
• Industrial Coatings: Imparts color to solvent-borne industrial and automotive coatings, where lightfastness and chemical resistance are required.
• Wood Stains and Polishes: Effective for coloring wood stains, polishes, and other decorative finishes that utilize organic solvent systems.
• Waxes and Greases: Employed as a colorant in petroleum-based products like lubricating greases and waxes for identification purposes.
• Fuel and Oil Marking: Suitable for use as a dye in non-aqueous marker systems for fuels and industrial oils.
