Description

Sodium dichromate is used as a strong oxidizing agent in organic synthesis. It is used in metal finishing as an aid of corrosion resistance, manufacture of inorganic chromate pigments and in the preparation of colored glass and ceramic glazes. It is used as a mordant for acidic dyes to improve their color-fast properties and as a corrosion inhibitor in undercoats and primers.

This Thermo Scientific Chemicals brand product was originally part of the Alfa Aesar product portfolio. Some documentation and label information may refer to the legacy brand. The original Alfa Aesar product / item code or SKU reference has not changed as a part of the brand transition to Thermo Scientific Chemicals.
