This is a light coloured dedusted powder modified to achieve minimum astringency and thus quick tannin penetration. Mimosa WS is a suitable pretanning agent for vegetable tanning.
For pre-tanning of vegetable tanned leathers 5% Mimosa WS is recommended 30mins before the main tan addition.
Mimosa WS is also recommended for softee / nappa leathers where it gives good fullness without impacting on the softness of the leather.
For this application 5% is recommended in the re-tannage.
