Low fogging
Fatliquors formulated to keep fogging values within the automotive standard without sacrificing softness.

Chemistry formulated for the automotive interior.
The most demanding leather there is
An automotive upholstery leather spends ten years inside a glass box in the sun. It has to survive thermal cycles from −30 °C to 110 °C, constant UV, permanent abrasion and the friction of thousands of entries and exits — without fading, hardening, cracking or releasing volatile compounds that fog the windscreen.
That last point — fogging — is the test that fails the most articles. Poorly formulated fatliquors migrate with heat, evaporate and condense on the inside of the glass. OEMs measure it against their own standard and do not negotiate the result.
On top of that comes the documentation. The automotive sector works with ever-tighter restricted substances lists: bisphenols, free aldehydes, heavy metals, chromium VI. Every batch of leather ships with analysis, and every input has to be able to back it up.
JOHE distributes the Silvateam line developed specifically for this process: wet white and wet blue tannage and retannage for automotive, replacement syntans for tight leathers with embossing retention, and low-fogging fatliquors. It is the same chemistry used by the tanneries supplying European OEMs. In our laboratory we run the application trials to validate it in your process.
