Field of application

Cationic fatliquor for the chrome tannage and for the final application into the fatliquoring bath. In rechroming it gives a proper wet back with the natural smooth grain. It supports the uniform uptake of the chrome or the chrome syntan. In topping it provides surface touch for the heavy retan crust, which has to be vacuum dried.



  • good lightfastness
  • improves grain smoothness and elasticity in chrome tannage
  • slightly waxy feel
  • ensures exhaustion of anionic fatliquors
  • improves chrome distribution



    Licrol K 4 is added first in the chrome tanning process. For the exhaustion of the main fatliquor and for surface lubrication, Licrol K 4 is given after the formic acid.
