Chrome sulfate

CHEMICALCHARACTER: Basic Chromium Sulphate

analytical date:

Cr2O3: 24%0.5%



Neutral Salts:281%

Ph of 6% Solution: 3.00.2


chem-tan-basic chrome sulfate is a powder easily soluble in cold water and highly soluble in hot water in the proportion of 1:2.

It contains compatible additives to help fast penetration and better exhaustion. The product is made in such a way as to ensure a high degree of solubility in cold water. The tanner has the obvious advantage of controlling his masking by the addition of suitable masking agents. The basicity variation from batch to batch is very minimal and one can be assured of a starting material of standard basicity.


Because of the ease of solubility, this can be used in dry tannage or floatless tannage without any problem. The product could also be dissolved in water in the proportion of 1:2 and used for tannages where definite floats are employed. Since they are not masked, the tanner can add the requisite amount of masking agent which has the advantage of controlled and uniform dyeing at the later stage. As such, when used, it gives an optimum bluish green color and uniform tanning is achieved.
