Flammability and Explosibility

Nonflammable

Properties and Applications

blue light green. Soluble in water for the green, solubility of 20 g/L (80 ~ 85 ℃), insoluble in organic solvents. The strong sulfuric acid for yellow green, dark blue after diluted precipitation, with zinc and ammonia reduction for green light yellow. In dyeing of copper (colored light yellow, iron ion in a dark colored. Is very sensitive to that fights. Can be used for cotton, viscose, silk and PVA/rayon blended fabric dyeing and printing directly, also used in leather, paper and regenerated celluloee fiber film color.
