Chrome Alum, or Chromium Potassium Sulphate, is a double salt used in metal finishing, leather processing, and specialty surface treatments. In electroplating and metal preparation, it serves as a source of trivalent chromium, offering controlled tanning and mild passivation effects without the aggressive behaviour of hexavalent systems.
Indian‑origin Chrome Alum provides consistent crystal quality and solubility, making it suitable for formulators seeking stable, reproducible performance in both wet‑end processes and auxiliary treatments.
| Sr. No. | Description | Specification |
|---|---|---|
| 1 | Purity | Technical/industrial grade |

Stable when stored dry and protected from excessive heat
Source of trivalent chromium in certain plating and surface treatment formulations
Auxiliary agent in etching, pickling, and metal‑preparation processes
Intermediate for production of other chromium compounds
Contains trivalent chromium; handle to avoid dust generation and skin contact
Store in cool, dry areas away from incompatible materials such as strong alkalis
Use standard PPE (gloves, goggles, protective clothing) and good industrial hygiene
Dispose of chromium‑bearing wastes in accordance with environmental regulations
