Mimosa CR is a combination of a modified wattle extract and a chrome salt that delivers a water soluble veg/chrome powder ideal for grain tightening retannages with good fullness and softness. Leathers retanned with Mimosa CR exhibit better filling and tightness with smoother grains leading to improved buffing properties for a nubuck effect.
Mimosa CR has an inherent low pH and can be used prior to neutralisation.
Up to 5% can be used and helps give leathers a smooth, tight even grain.
Mimosa CR can also be used after dyeing and fatliquoring where it helps with the fixation process. Depending on the type of leather and required feel, between 5% and 10% of Mimosa CR can be used at this stage.
THE WORLD’S BEST
Mimosa extract is a very versatile tanning compound and can be used for tannage on its own or in combination with other tanning compounds. There are many speciality types of leather produced by combining Mimosa extract with other chemicals, such as chrome or organic tanning compounds, in pre-tannages or re-tannages.
