Usage

Description

SOLWAY BLUE RN is a dark blue powder that is soluble in ethanol, o-chlorophenol, and slightly soluble in acetone and pyridine. It is insoluble in chloroform and toluene. When it comes into contact with strong sulfuric acid, it turns purple. SOLWAY BLUE RN is used for dyeing wool, silk, polyamide fiber, and wool blends. It can also be used directly for printing on wool, silk, and polyamide fiber fabrics. Additionally, it is utilized in the coloring of leather, paper, soap, and wood. SOLWAY BLUE RN can be combined with C.I.Acid Green 50 to create Acid Blue BGA.
