Solvent Yellow 14

Solvent Yellow 14 which is also known as Oil Orange is one of our special products in the solvent dyes range. Our Solvent Yellow 14 (Oil Orange) has applications including coloring of polymers, plastics, RPVC, transparent paints, resins, SAN, oil separations, fibers, rubbers, wax, oils, lubricants, fuel, gasoline, candles, paint, printing inks.

Shaanxi Medibridge Biotech Co., Ltd. focuses on supplying high-quality ingredients with stable activity standards and reliable supply support for different industrial and formulation needs.

Solvent Yellow 14 belongs to the azo dye family. The azo group serves as its primary chromophore, enabling the absorption of specific visible light wavelengths and resulting in vivid yellow to orange-yellow hues.

Its structural characteristics confer the following material properties:

• Good oil solubility: Suitable for use in mineral oils, lubricating oils, waxes, oil-based resins, and certain organic solvent systems.
• High transparency in coloration: Compared to pigment-based colorants, Solvent Yellow 14 typically yields more transparent and uniform coloring results.
• Vibrant color: Ideal for industrial formulations requiring bright yellow or orange-yellow visual effects.
• Molecular-level coloration: Disperses in a dissolved state within suitable media, typically eliminating the need for grinding or mechanical dispersion processes.
• Good compatibility with oil-based systems: Suitable for specific formulations involving oils, inks, coatings, and plastics processing.

The fundamental basis for the application of Solvent Yellow 14 lies in its solubility within organic media. As a solvent dye, it typically functions not through particulate dispersion, but by dissolving into oily or organic phases to deliver transparent, uniform coloration.

Key factors to consider in practical applications include:

• Solvent Polarity

Solvent Yellow 14 exhibits varying solubility across different solvent systems. It generally performs well in oily media, aromatic hydrocarbons, esters, ketones, and certain resin systems.

• Dissolution Temperature

Raising the temperature appropriately usually helps accelerate the dissolution rate and improve system uniformity.

• Addition Ratio

Due to its high tinting strength, a distinct yellow effect can be achieved with low dosage levels. The actual amount added should be adjusted based on the target color depth, transparency, and cost requirements.

• System Compatibility

Care must be taken to avoid issues such as precipitation, turbidity, sedimentation, or color deviation caused by incompatibilities between the dye and the resins, additives, or solvents.

• Transparency Requirements

Its advantages in transparent coloration are particularly evident in applications such as transparent inks, the dyeing of oil-based products, wax products, and transparent plastic systems.

Solvent Yellow 14 typically exhibits a hue ranging from vivid yellow to orange-yellow. In oil-based systems, it imparts a bright, transparent, and uniform yellow appearance to the substrate.

Its color performance characteristics include:

• High color brightness: Suitable for formulations requiring vivid yellow or orange-yellow shades.
• Good transparency: Ideal for coloring transparent or translucent materials.
• Strong tinting strength: Significant color depth can be achieved with low dosage levels.
• Good blending capability: Can be combined with other oil-soluble dyes to create orange, brown, golden-yellow, and reddish-yellow shades.
• Clear hue: Produces a clean, bright yellow visual effect in suitable systems.

Compared to yellow pigments, Solvent Yellow 14 is better suited for applications requiring transparency, uniformity, and a solution-based coloring effect; conversely, if high opacity is required, pigment-based products should be selected or used in combination with pigments.

Solvent Yellow 14 is suitable for use in certain plastic and resin processing systems; however, as it is a dye-based colorant, its actual thermal stability and migration characteristics must be evaluated in the context of the specific material system.

Key aspects to examine during R&D and application testing include:

• Color change at processing temperatures
• Color stability following heat treatment
• Occurrence of blooming or migration
• Compatibility with the resin system
• Color uniformity in transparent plastics
• Color retention after long-term thermal aging

For applications involving plastics, resins, and high-temperature processing, customers are advised to conduct small-scale and pilot-scale trials prior to mass production. Particular attention should be paid to testing migration and heat resistance-especially when dealing with high-temperature engineering plastics, transparent plastics, flexible PVC, or systems containing plasticizers.

• Coloring of Industrial Oils

Solvent Yellow 14 is suitable for coloring certain industrial oils and oil-based media.

Its advantages include excellent oil solubility, vibrant color, low dosage requirements, and uniform coloration.

• Coloring of Wax Products

In wax-based systems, Solvent Yellow 14 can be used for:

Industrial waxes, paraffin wax, candles, polishing waxes, and decorative wax products.

Its transparent yellow to orange-yellow hue makes it ideal for formulating warm-toned, golden-yellow, and orange-yellow wax products.

• Coloring of Plastics and Resins

Solvent Yellow 14 is applicable to certain plastic and resin systems, particularly those requiring transparent colors. However, in practical applications, factors such as heat resistance, migration properties, and regulatory compliance should be carefully evaluated.

• Inks and Coatings

Solvent Yellow 14 can be used in certain solvent-based inks, oil-based paints, and specialized industrial coating systems, primarily to provide transparent yellow to orange-yellow effects.
