Acid Brown 85
CAS:Acid Brown 85 is a reactive dye that is used to color paper, textiles and leather. It is an azo dye, which means it contains a benzene ring with two nitrogen atoms in the 1- and 2-positions. Acid Brown 85 is soluble in water and has good dispersibility. It can be used as an extender for other dyes or as a reactive dye for cellulose fibers. Acid Brown 85 may also be used as a pigment in paints and varnishes. The product has low energy reactivity, meaning it does not need to be heated before use.
Purity:Min. 95%
