What is Solvent Red 195?

Solvent Red 195 is an oil-soluble solvent dye used for coloring fuels, lubricants, plastics, waxes, and other hydrocarbon-based systems. It dissolves directly in compatible organic media and produces a bright red transparent coloration.

This dye is known for its strong tinting strength, good solubility in oils and organic solvents, and stable performance in industrial formulations. It is widely used in fuel identification, lubricant coloring, and transparent plastic applications where clarity and vivid color are required.

Key Performance Properties

1. Excellent Solubility in Hydrocarbon Systems

The dye dissolves effectively in oils, fuels, and organic solvents, ensuring uniform coloration without dispersion issues.

2. Strong Tinting Strength

Solvent Red 195 delivers high color intensity even at low dosage levels, supporting cost-efficient formulations.

3. Transparent Coloration

It produces bright and transparent red shades, making it suitable for applications where clarity is important.

4. Good Processing Stability

The dye maintains stable performance under typical industrial processing conditions in both liquid and thermoplastic systems.

Advantage

1. Effective for Fuel and Oil Identification

It provides consistent and visible coloration for fuels and lubricants used in identification systems.

2. Suitable for Transparent Plastic Applications

The dye enables coloration without significantly affecting transparency in compatible materials.

3. Easy Processing

Since it dissolves directly into the medium, no additional dispersion process is required.

Typical Limitations

1. Moderate Lightfastness

Compared with high-performance pigments, solvent dyes generally have lower resistance to long-term UV exposure.

2. Potential Migration in Some Plastics

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

3. Limited Hiding Power

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