Solvent oil red 24 OSH
Solvent Oil Red 24 OSH is a bright, oil-soluble azo dye used primarily for coloring petroleum-based solvents, oils, waxes, and greases. Known for its excellent solubility in hydrocarbon mediums, this dye delivers a vivid red hue with good thermal stability and moderate lightfastness. Its OSH (Oil Soluble High) formulation ensures optimized dispersion in non-polar systems.
Solvent Oil Red 24 OSH is used in applications requiring visual identification, fuel marking, and product differentiation across industrial environments. It is available in powdered or granulated form and is manufactured to meet industrial-grade quality standards.
