Solvent Orange 7

Solvent Orange 7 is a high-performance solvent dye engineered for vibrant orange coloration in solvent-based inks, coatings, plastics and specialty industrial applications. It delivers excellent tinctorial strength, rapid solubility in common organic solvents, and stable color reproduction across batches. Solvent Orange 7 is optimized for formulations where vivid hue, solvent compatibility, and processing stability are required.

Key Properties

• High tinting strength and vivid orange chroma.
• Good solubility in ketones, esters, aromatics, and many chlorinated/oxygenated solvents.
• Low tendency to precipitation under normal processing conditions.
• Good compatibility with most solvent-borne resins (alkyds, nitrocellulose, acrylics, polyurethanes) and plasticizers.

• Stable color under typical thermal processing and short-term light exposure (formulation-dependent).

Why Choose Our Solvent Orange 7

We offer sample packs, lab support for shade matching, formulation troubleshooting, and custom liquid concentrates/masterbatches. For migration-sensitive applications or regulatory queries (REACH/food contact), request application-specific testing and certificates.

Applications

mainly used in coloring all kinds of plastics,such as PS,HIPS,ABS,PMMA,AS,PET,RPVC,SAN,PC, PA6,etc. Also used in candles, inks, particularly to the staining of petroleum products, as well as to brightening agents.

Solubility & Compatibility Notes

Solvent Orange 7 shows rapid dissolution in polar aprotic solvents such as methyl ethyl ketone (MEK), acetone, ethyl acetate and many aromatic hydrocarbons. In blends of solvents, solubility is generally improved; however, solvent polarity and resin interactions will determine final clarity and migration behavior. Pre-dissolving the dye into a concentrated solvent carrier (making a liquid color concentrate) often improves dispersion and color consistency in production.

Safety, Handling & Storage

• Handle under standard chemical safety practices: protective gloves, goggles and adequate ventilation.
• Store in tightly sealed containers away from direct sunlight and moisture, at ambient temperature (preferably 5–25°C).
• Provide SDS with product shipments and ensure downstream users have access to regulatory and hazard information. Do not dispose via drain; follow local disposal regulations.

Packaging & Availability

Available in 25 kg, 50 kg and bulk packaging (jumbo bags / IBC depending on supply). Custom packing and private-label options can be arranged for large-volume customers. Lead times depend on order size and current inventory.
