Solvent Red 52 is an oil-soluble solvent dye commonly 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 bright red transparent coloration.
The dye is valued for its strong tinting strength, good solubility in oils and organic solvents, and stable color performance in industrial formulations. It is widely used in liquid systems for color identification and in plastics where transparent red shades are required.
Solvent Red 52 CorSol®3552 ⬇️TDS
This is a bluish red solvent dye recommended for plastics such as PS, SAN, PMMA, PC, PET, PA6, ABS and ABS/PC blends, with potential suitability for PA66, offering stable processing performance and consistent coloration in industrial applications.

The dye dissolves well in oils, fuels, and organic solvents, ensuring uniform coloration without sedimentation.
Solvent Red 52 provides strong color intensity even at relatively low dosage levels, allowing efficient formulation.
Unlike pigments, solvent dyes create transparent color effects, making them suitable for clear or translucent materials.
The dye maintains stable color performance under typical industrial processing conditions used in oils and thermoplastic systems.
The dye is often used to provide visible color identification in fuels and lubricant systems.
It provides bright red coloration while maintaining clarity in compatible materials.
Since the dye dissolves directly in compatible systems, dispersion steps required for pigments are not necessary.
Solvent dyes generally provide lower outdoor durability compared with high-performance pigments.
Migration resistance depends 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.
