TECHNICAL ASPECTS


Chrome tanning is the most versatile and offers advantages such as a better fixation of all the anionic products used in retanning, a greater intensity of dark tints and a better exhaustion of residual baths.
The choice among the various chromium-based tanning agents, is based on the characteristics sought. Some items require greater dye reactivity to enhance optical effects, such as the classic cloudy appearance of a “sauvage” article.
A basification of chrome tanning that does not dampen the reactivity of the tanning helps to consolidate these characteristics.

A masked tanning instead offers the advantage of a greater fullness of the leather with a more even distribution of the anionic products.



LECROM AL


LECROM AL is a double chrome-aluminum salt. It gives a reactivity superior to the support and a less elastic grain. It is suitable for chrome tanning and retanning articles where you want the dyes to stand out and to obtain a less elastic and tear resistant grain. The combination of metals optimizes the exhaustion of the tanning baths.
