Product Description:

Ranbar Blue SR5028-2 is a triphenylmethane dye acid blue 9. This dye appears as a blue-purple powder, readily soluble in water, and its solution in water is green-blue. Upon addition of sodium hydroxide, it becomes colorless with the emergence of deep purple precipitates. In concentrated sulfuric acid, this acidic dye exhibits an orange hue, which lightens to a pale yellow upon dilution.

Ranbar Blue SR5028-2 possesses vibrant color, strong dyeing power, and excellent evenness in dyeing. However, it is sensitive to copper and iron ions, requiring careful attention during the dyeing process to prevent any adverse effects on the color outcome.

Ranbar SR5028-2 Acid Blue 9 dye is primarily used in the textile processing industry, suitable for dyeing and printing of wool, silk, nylon fibers, polyamide, and wool-blend fabrics. It can also be employed for coloring leather, paper, wood, glasswater, cleaning agents, and other applications.
