TRUPON KLZ has good lubricating and softening properties showing at the same time an excellent penetration and distribution in the leather, both on chrome and highly retanned leathers .

TRUPON KLZ can be used as unique fatliquor in articles requiring firm handle (corrected grain, ….) but mainly will be used in combination with other fatliquors from our range. We recommend combinations with TRUPON PLZ and/or TRUPON DXZ depending on touches and desired effects.

TRUPON KLZ should be prepared for use by adding it 3-4 five times its own weight of water at 40/50ºC obtaining a very stable opal emulsion.

Leathers fatliquored with TRUPON KLZ show good dyeing behaviour in terms of intensity and levelling.

TRUPON KLZ exhibits an excellent acid stability and also in presence of hard waters or even slightly salted waters. When there are these unfavourable conditions the behaviour of TRUPON KLZ is much better than any usual sulphated natural oil. As a results, the leather will show always a dryer touch and brilliant and even dyeing.

Leathers fatliquored with TRUPON KLZ doesn’t have tendency to give repouse and show good light and heat yellowing. Fastness.


Depending on the articles and combinations:  4% -  8% on shaved weight

Storage Stability: TRUPON KLZ can be stored for up to one year, if temperatures below 5ºC and above 40ºC can be avoided. On prolonged storage or extremes of temperature TRUPON KLZ may exhibits some settlement which can be rectified by  stirring the product thoroughly before use.
