Product Description:
Ranbar Orange D251 metal complex dyestuff is a yellowish orange azo chromium complex dyestuff with bright color, high transparency, no heavy metals, good solubility in organic solvents, good compatibility with most resins, good light resistance, heat stability, acid and alkali resistance and very high dyeing strength.

Ranbar Orange D251 azo chromium complex dyes are widely used in various paints, coatings, printing inks, color pastes, wood stains, leather dyeing, shoe polish coloring, aluminum foil coloring, foil stamping coloring, metal coloring (low-temperature baking finishes), pen refills and stationery inks, plastic coating (vacuum plating), special coatings, etc.

Tips: Due to the high concentration of dyestuff, the color of the dye color powder differs greatly from the actual coloring color, the actual coloring color can refer to the color card, and the actual application to show the effect shall prevail.
