Trade Name: YOBISOL ORANGE RLSE · CI Number: Solvent Orange 62
Solvent Orange 62 earns its position in demanding applications through two properties that most orange dyes cannot deliver simultaneously: heat stability to 200°C and light fastness of 6–7 on the blue wool scale. That combination is why it appears in engineering plastic applications where processing temperatures exceed what standard azo oranges can withstand without shade shift, and in outdoor-exposed coatings where UV degradation would fade a lower-fastness alternative inside a single season. The shade character is a deep, rich orange — no brown bias, no yellow cast at standard loadings — which makes it reliable in colour-matching without tonal correction.
Polyolefin and polycarbonate processors specify it for parts that will live in automotive exteriors, agricultural equipment, and safety signage where colour retention over years of field exposure is part of the product specification. Migration resistance in rigid PVC and polystyrene is good, meaning the dye stays where it was put rather than diffusing into adjacent white or light-coloured components during long-term contact at elevated service temperatures. In solvent-based coatings, it dissolves cleanly in aromatic hydrocarbons, esters, and alcohols with good solution stability at working concentrations. Wax and candle formulators benefit from its clean melt dissolution and even distribution through the wax mass. Available from Yobai Industries as YOBISOL ORANGE RLSE, batch-tested for colour strength and heat stability before every dispatch.

Solvent Orange 62 is a perinone-class dye with a higher molecular weight than standard azo oranges, which delivers better heat and light stability at the cost of slightly reduced compatibility with aliphatic systems. It dissolves readily in aromatic hydrocarbons — xylene and toluene are the preferred dissolution media — giving stable, haze-free solutions at concentrations relevant to most industrial coatings and plastics applications.
For plastics colouring, pre-disperse the dye in a carrier resin or masterbatch before introduction to the main polymer. For coating systems, dissolve in xylene or ethyl acetate at 40–60°C with continuous stirring before adding to the formulation. Attempting direct dissolution in aliphatic systems will yield poor results. If your formulation requires aliphatic compatibility, contact us for a grade recommendation suited to that system.
All loadings are by weight of dye relative to the substrate or formulation. Start at the low end of the range and adjust upward to shade. Solvent Orange 62 has high tinctorial strength — over-loading increases migration risk and reduces transparency.
| Application | Loading (% wt) | Solvent System | Processing Temp | Notes |
|---|---|---|---|---|
| Engineering Plastics | 0.05–0.5% | Melt (no solvent) | 220–300°C | Pre-compound in masterbatch; verify migration in contact applications |
| High-Temp Coatings | 0.1–2% | Xylene / aromatic naphtha | 20–80°C | Dissolve at 40–60°C before adding to binder |
| Printing Inks | 0.5–3% | Aromatic solvents / esters | 20–60°C | High tinctorial strength; start at 0.5% for tints |
| Wax & Candles | 0.05–0.3% | Paraffin melt | 60–80°C | Add to melt at 70°C with stirring; cool slowly for uniform colour |

The shade depth achievable with Solvent Orange 62 depends on loading rate, substrate, and film thickness. The following representative tones reflect standard loading ranges in coatings and plastics applications.
Shade appearance varies with substrate, solvent system, film thickness, and backing colour. Request a sample for colour-critical matching before committing to production.
