Solvent Red 24 is an oil-soluble solvent dye widely used for coloring fuels, lubricants, plastics, waxes, and other hydrocarbon-based materials. Unlike pigments, solvent dyes dissolve directly in compatible organic media, producing bright and transparent red coloration.
This dye is valued for its strong tinting strength, good solubility, and stable shade performance in industrial formulations. It is commonly used for color identification in fuels and lubricants, as well as for transparent coloration in plastics and resins.

Solvent Red 24 is commonly used in the following applications:
Fuel coloring
Lubricants and industrial oils
Waxes and hydrocarbon systems
Plastics and synthetic resins
Industrial inks
Specialty coatings
In fuel and lubricant systems, the dye provides clear color identification, while in plastics it enables transparent red coloration without significantly affecting material clarity.

The dye dissolves well in oils, fuels, and organic solvents, ensuring uniform coloration without particle dispersion.
Solvent Red 24 provides high color intensity even at relatively low dosage levels, helping optimize formulation efficiency.
Because the dye dissolves directly in the medium, it produces bright and transparent red shades suitable for clear or translucent materials.
The dye maintains stable color performance during typical industrial processing conditions used for oils and thermoplastic materials.
The dye is commonly used to provide visible color identification in fuel and lubricant systems.
It produces bright red coloration while maintaining clarity in compatible materials.
Because it dissolves directly into compatible systems, dispersion processes required for pigments are not necessary.

Compared with high-performance pigment systems, solvent dyes generally provide lower resistance to long-term outdoor exposure.
Migration resistance may vary depending on the compatibility between the dye and the polymer system.
As a dye, it does not provide opacity and is not suitable for applications requiring strong covering power.
When selecting solvent dyes for industrial applications, buyers should confirm:
Target application (fuel, lubricants, plastics, etc.)
Solubility requirements
Processing temperature
Desired shade intensity
Regulatory compliance requirements
Providing clear application information helps suppliers recommend suitable grades and usage conditions.

It is commonly used for coloring fuels, lubricants, plastics, waxes, and other hydrocarbon-based systems.
Yes. The dye dissolves well in many oils, fuels, and organic solvents.
Yes. It can provide transparent red coloration in compatible thermoplastic materials.
Solvent dyes dissolve in the medium and produce transparent coloration, while pigments remain dispersed and provide opacity.
It is generally not recommended for long-term outdoor exposure due to moderate lightfastness compared with pigment systems.
