What is Solvent Blue 104?

Solvent Blue 104 is an oil-soluble solvent dye widely used for coloring fuels, lubricants, plastics, waxes, and other hydrocarbon-based systems. It dissolves directly in organic media, producing bright blue transparent coloration with high tinting strength.

This dye is commonly applied in industrial formulations where clear color identification, uniform dispersion at the molecular level, and stable processing performance are required. It is especially suitable for liquid systems and certain thermoplastics where transparency is important.

Product Technical Data

Solvent Blue 104 CorSol®3604 ⬇️TDS
Solvent Blue 104 CorSol®3604 is a high-performance solvent dye that delivers a clear and intense blue shade. It features excellent thermal stability up to 280°C, making it suitable for high-temperature processing conditions. The product shows good solubility in organic solvents and provides uniform coloration with high color strength. It is mainly used for coloring polystyrene (PS) and is also suitable as an intermediate for the production of C.I. Acid Blue 80, offering both application versatility and reliable performance.

Key Performance Properties

1. Excellent Solubility in Hydrocarbon Systems

The dye dissolves well in oils, fuels, and organic solvents, ensuring uniform coloration without the need for dispersion.

2. Strong Tinting Strength

Solvent Blue 104 delivers high color intensity at low dosage levels, making it efficient for industrial formulations.

3. Transparent Coloration

As a solvent dye, it produces bright, transparent blue shades suitable for clear or translucent materials.

4. Good Processing Stability

The dye maintains stable color performance under standard industrial processing conditions for oils and thermoplastics.

Advantage

1. Suitable for Fuel and Oil Identification

Provides consistent and visible blue coloration in hydrocarbon-based systems.

2. Maintains Material Transparency

Ideal for applications where clear or translucent appearance must be preserved.

3. Easy to Use in Formulations

Direct solubility eliminates the need for complex dispersion processes.

Typical Limitations

1. Moderate Lightfastness

Compared with pigments, solvent dyes generally have lower resistance to prolonged UV exposure.

2. Potential Migration in Some Plastics

Migration behavior depends on the compatibility between the dye and the polymer system.

3. No Hiding Power

As a dye, it does not provide opacity and is not suitable for applications requiring full coverage.
