Solvent Brown 20
Solvent Brown 20 (C.I. 26155) is an oil-soluble brown dye that is completely insoluble in water, but dissolves readily in esters, ketones, aromatics, oil-based resins, and wax systems. It can be blended with Solvent Black dyes to deepen the color and create a steady, dark brown tone. Often used as a base brown, it is ideal for wood grain, leather, retro-industrial, and coffee-toned color schemes.
