Product Inquiry

Ferro’s Curticrom Basic Chrome Sulfate powder is produced in a closed loop system, which helps minimize our impact on the planet and provides for high quality and enhanced performance.  It is a non-toxic Cr (VI) free powder that easily dissolves in water, exhibits stable basicity and pH, and has a low amount of insoluble materials.

As a tanning agent, Basic Chrome Sulfate powder shows excellent penetration capabilities and guarantees a high-quality wet blue. It also provides uniform chromium oxide distribution on the cross section and the grain of the leather. In chrome plating, Curticrom Basic Chrome Sulfate is a cost-effective, Cr (VI)-free source of chrome. 

The powder form is the most stable form and it is easy to transport and store, making it the most broadly used version.
