Solvent Orange 107

 

Solvent Orange 107 is a high-performance solvent dye (CAS 71872-79-0) with brilliant reddish-orange coloration. Specifically engineered for technical applications, it demonstrates: 1) Exceptional thermal stability (300°C), making it ideal for engineering plastics like ABS, PC, and automotive coatings; 2) Superior lightfastness (Grade 7-8 per ISO 105-B02), ensuring color retention in outdoor applications; 3) Excellent solubility in alcohols, ketones, and aromatic hydrocarbons, facilitating easy incorporation; 4) Regulatory compliance with REACH, FDA 21 CFR 178.3297, and OEKO-TEX® standards. Particularly valued for automotive signal lights and safety equipment where color stability is critical. Offers 20% higher chromatic intensity than conventional alternatives, reducing usage costs. Batch-to-batch consistency guaranteed (ΔE<0.8).

Solvent dyes are used to color organic solvents, hydrocarbon fuels, waxes, lubricants, plastics, and other hydrocarbon-based nonpolar materials. Fuel dyes are one use of solvent dyes. Their molecules are typically nonpolar or little polar, and they do not undergo ionization. They are insoluble in water. They form a colloidal solution in solvents. They have poor to good light fastness.
