Application & Recommendation

Rockytan AL can be used in production of white leathers, fixing dyestuffs and increasing dyeing brilliance. It also improves nubuck and suede due to good buffability.

Rockytan AL is compatible with mineral tanning agents. It’s also has limited compatibility with anionic tanning agents and dyestuffs.

If Rockytan AL is used along with chrome tanning agents in the main tannery stage, the produced leather will have a very light color and a very fine flat grain.
 In the retanning based on the shaved weight:
1-3 % Rockytan AL

 For increasing the color shade after the fixing with acid:
0.3-1 % Rockytan AL

 For fixation of hydrophobic agents:
2-3 % Rockytan AL
