Rockytan RRN

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 the 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 a 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 achieved 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).
