Mixture of protein based compounds

UNITAN FILL is a protein-based filler for filling the empty parts of the leathers and can be used for many types of leathers. It can be utilised for chrome and vegetable retanned leathers in combination with synthetic and vegetable extracts. For high exhaustion of UNITAN FILL, it is preferably added into the fatliquoring bath just before the addition of fatliquor mixture into the drum.
