Properties:

CHEMITAN B

  • CHEMITAN B  is a high quality replacement syntan for the production of white and pastel shade chrome leathers.  Self-tannage with CHEMITAN B produces extremely white lightfast leathers with mild, full handle. The leather exhibits a tight and fine grain.

  • CHEMITAN B  has a strong bleaching effect and hence its addition in the retannage of vegetable tanned leathers improves the color of the leather and also disperses the vegetable tannins more evenly and deeper into the leather, thereby giving a softer and more uniform feel.

  • As its astringency is very low, part of the retanning with CHEMITAN B can be given before neutralization. This improves the whiteness of the leather even further.

  • Chrome leathers retanned with CHEMITAN B possess good fullness and the grain is smooth and resilient which can be very finely buffed making it an ideal choice for Suede and Nubuck.  The tendency of leather  to yellow under conditions of light and heat is low.

Application metod:

CHEMITAN B

  • CHEMITAN B  is preferably added to the tanning drum in undissolved state.

  • CHEMITAN B can be used either alone or in combination with other anionic retanning agents during the retannage of chrome leather.

  • It has a medium filling action. Better filling is obtained by combining it with resin tanning materials such as CHEMITAN R, even in the processing of white or pastel shade leathers.

  • The retannage of vegetable tanned leathers with CHEMITAN B not only improves the grain properties and imparts better fullness and softness but also bleaches the leather color quite appreciably.
