Rockytan RHN has a very low astringency, thus it imparts a grain smoothness and fineness. As it has good stability to electrolytes, thus it is suitable for all procedures. It promotes brilliant, intense shades. Retanning with Rockytan RHN completes the chrome tanning, so different wet blues can be largely normalized. Also it can be used in pretanning and tanning, so gives a good handle and outstanding dye ability.

General: 1-3 % prior to neutralization (based on shaved weight).
Pretanning: 1-2% after pickling (based on pelt weight) in the same bath.
