Rockytan
RRN can be used in tanning and retanning of white leathers together with
chrome powder. If used in mineral tanning, it accelerates penetration and
improves dispersion of tanning agents. Also it imparts a tighter and denser
grain to leathers tanned or retanned with this product and in suede leathers
gives finer nap. |

Application & Recommendation |
|
|
|
|
Rockytan
RRN is soluble even in cold water and its solutions are compatible with
acids, salts and chrome tanning agents. If used alone for tanning, it gives a
white leather and in tanning wool skins, a comparatively pale leather is
acheived without greening the wool. The consumption rate is about 2-3% in
tanning (together with 5-6% chrome powder) and 2-4% in retanning (before
neutralization). |
