Description

Sodium dichromate is an important basic chemical raw material. It is used as auxiliary in printing and dyeing industry, electroplating industry and leather industry.

It has special coloring ability and is widely used in glass coloring and fabric dyeing. Used as an oxidant for aniline dyestuff dyeing in printing and dyeing industry, a post-treatment agent for curing VAT dyestuff dyeing, and a mordant for acid mordant dyestuff dyeing. It is also used to color VAT dyes that are difficult to oxidize, and fast pigment dyestuff printing reserving agent.

In the process of printing and dyeing, trivalent chromium is produced by reduction of sodium bichromate, so as to improve dyeing fastness of mordant dyes.
