Methylene Blue Zinc Free Solvent Dyes

Methylene Blue Zinc Free Solvent Dyes are cationic by composition. Stability of their chemical characteristics remains unaffected when these are diluted in normal water at room temperature. These basic dyes are produced by oxidizing N-dimethyl-phenylenediamine, nitrogen and sodium dichromate at specific temperature range. Offered dyes have 300 degree C heat resistance capacity and their density is 1.28 g/cm3. Light fastness of these dyes ranges between 7 to 8. It is suitable for coloring papers, leather and fabrics (wool, silk and cotton).
