Solvent Orange 60

Solvent Orange 60 is a synthetic oil-soluble dye belonging to the solvent dye family. It is mainly used to impart a bright, transparent orange shade to non-polar systems where water-soluble dyes are not suitable. 

Solvent Orange 60 is characterized by excellent solubility in organic solvents, good heat resistance, and stable coloration in plastics and coatings. Because it dissolves completely at the molecular level, it provides clear, uniform, and high-gloss color effects without particle dispersion issues.

In industrial use, Solvent Orange 60 is favored for its good compatibility with resins, easy processing, and reliable color performance, making it a practical choice for manufacturers seeking vivid orange shades in solvent-based systems.

Characteristics and Advantages

Solvent Orange 60 combines excellent coloring performance and environmental adaptability, and its main advantages are reflected in the following aspects:

• Vivid color and strong tinting power: It presents a bright orange to golden-orange shade with high color saturation. The recommended dosage in plastics and fibers is only 0.01%-0.06%, and the tinting uniformity error is less than 5% (The Colour Index International, 2024).
• Superior heat resistance: It can withstand processing temperatures of 240℃-280℃, which is suitable for high-temperature molding processes of engineering plastics. For example, when coloring polyamide (PA66) and polyester (PET), it maintains stable color without fading even at 260℃ (GB/T 38994-2020).
• Excellent light and weather resistance: Rated 6-7 on the 1-8 light fastness scale, it can resist UV erosion for a long time. In outdoor applications (such as automotive exterior trim), the color retention rate is still over 85% after 500 hours of xenon lamp aging test (ASTM G155-13).
• Broad solubility and compatibility: It dissolves well in aromatic solvents (solubility in toluene is ≥1.5 g/L at 25℃) and has good compatibility with various polymers (PS, ABS, PC, PET) and synthetic fibers (polyester, nylon). It does not cause substrate cracking or performance degradation (Chemical Abstracts Service, 2025).
• Strong chemical stability: It has acid and alkali resistance of level 5, and remains stable in the pH range of 4-10. It is not reactive with common plasticizers, antioxidants and other additives, and has migration resistance of level 4-5 (The Colour Index International, 2024).
• Environmentally friendly compliance: It does not contain banned aromatic amines (detection limit<10 ppm) and heavy metals (lead ≤5 ppm, cadmium ≤2 ppm), complying with EU REACH Regulation (Annex XVII) and OEKO-TEX® Standard 100 (2024 version).

Applications

Solvent Orange 60 is commonly used in:

• Plastics coloring: PS, HIPS, ABS, PMMA, AS, PET, RPVC, SAN
• Printing inks (oil-based)
• Smoke dyes and safety testing dyes
• Oil products, stationery & specialty applications
