PROPERTIES |
|
ANCHROME-S is a powder easily soluble in cold water and highly soluble
in hotwater 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. |
|
APPLICATION |
|
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 colour and uniform
tanning is achieved. |
