Solvent Black 7 is an oil-soluble solvent dye widely used for coloring fuels, lubricants, plastics, waxes, and other hydrocarbon-based systems. As a solvent dye, it dissolves directly in compatible organic media and produces deep black transparent coloration.
The dye is valued for its strong tinting strength, good solubility in oils and organic solvents, and stable performance in industrial formulations. It is commonly used in liquid systems for identification purposes and in plastics where transparent or translucent black coloration is required.
SBK7 – CorSol®6707 ⬇️TDS
This is a reddish-black pigment with good coloring and insulating properties, widely used in rubber, high-grade insulating bakelite, carbon paper, shoe polish, coatings, inks, plastics, leather, sealants, and electronic equipment (e.g., black matrix colorants).
Solvent Black 7 is commonly used in the following applications:
In liquid systems, the dye provides clear color identification, while in plastics it enables transparent black coloration without heavy opacity.

The dye dissolves well in oils, fuels, and many organic solvents, enabling uniform coloration without particle dispersion.
Solvent Black 7 provides strong color intensity even at relatively low dosage levels, supporting efficient formulation.
Depending on dosage level and application system, the dye can provide translucent to deep black shades.
The dye maintains stable color performance during typical industrial processing conditions used in oils and thermoplastic systems.
The dye is widely used to provide visible color differentiation in fuels and lubricant systems.
Because it dissolves directly in compatible systems, dispersion steps required for pigments are not necessary.
It can be applied across oils, plastics, waxes, inks, and other solvent-based systems.
Compared with high-performance black pigments, solvent dyes generally provide lower resistance to long-term outdoor exposure.
Migration resistance depends on polymer compatibility and formulation design.
As a dye, it does not provide the same opacity as carbon black or pigment-based black systems.
When selecting solvent dyes for industrial use, buyers should confirm:
Providing clear application information helps suppliers recommend suitable grades and usage conditions.

It is commonly used for coloring fuels, lubricants, plastics, waxes, inks, and hydrocarbon-based systems.
Yes. The dye dissolves well in many oils, fuels, and organic solvents.
Yes. It can provide transparent to deep black coloration in compatible thermoplastic systems.
Solvent Black 7 dissolves in the medium and can provide transparent coloration, while carbon black is a pigment that provides strong opacity and covering power.
It is generally not recommended for long-term outdoor exposure due to moderate lightfastness compared with pigment-based black systems.
