Tankrom® AB
Sisecam Dis Ticaret A. S.
Product Overview
Tankrom® AB is an inorganically reduced conventional Chrome Tanning Agent (33% Basicity).
Tankrom® AB has strong sulphate masking and is anionic in nature which is important to:
Accelerates chromium penetration.
Prevent possibility of appearance of irregular chromium oxide distribution on the cross section and the grain of the leather due to fast and irregular basification.
When Tankrom® AB is used in powder form, it is at anionic character (negative charged) and penetrates into the pelt without interaction with negatively charged groups of collagen. Anionic character is gradually transformed into cationic character. During this transformation, chromium complexes are fixed to the carboxyl groups of collagen. Fixation is accelerated and completed by basification.
Technical Properties
Chromium Oxide Content (%) : 25.5
Schorlemmer Basicity (%) : 33.0
pH (10% solution) : 3.0
APPLICATION
Tankrom® AB is readily soluble even in cold water and should be used in powder form. In main tanning and retanning, Tankrom® AB can be applied to all kinds of leather and is used 6-10% on pelt weight for pickled hide and skin and 15-25 g/L for pickled double-face (fur).
For successful chrome tanning, some tanning conditions such as bath length, bath temperature, basification and tanning time are important besides the type and amount of basic chromium sulphate used.
