TRUPON KL 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.

TRUPON KL has a high emulsifying power. It can easily incorporate up to 100% of its own weight in crude oil type TRUPON CST or TRUPON PB, being possible in this way to obtain a wide range of effects.

TRUPON KL 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 .

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

TRUPON KL 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 KL is much better than any usual sulphated natural oil.

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


TRUPON KL is the fatliquor of choice for any type of chrome leather or retanned chrome leather whenever the desired qualities were a soft touch, good feel and brilliant and exhausted dyeings.

TRUPON KL is perfectly suitable for white leathers or with clear colours.

Storage Stability: TRUPON KL 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 KL may exhibits some settlement which can be rectified by  stirring the product thoroughly before use.
