Astringent extracts

The astringent extracts of Saviotan Leather are used mostly in the traditional slow tanning made in tanks, but they can be used in fast tanning too. Thanks to their chemical characteristics, the astringent extracts provide the leather with better wear resistance. They increase the waterproofing but, at the same time, they let the sole breathes, allowing the oxygen exchange with the external.
