TRUPOSOL WBF is a sulphated anionic fatliquor which has been specifically developed for use in the production of wet blue intended for final use as automotive upholstery leather.

TRUPOSOL WBF possesses outstanding electrolyte stability and can be used at the pickling or chrome tanning stage. TRUPOSOL WBF will help in obtaining clean smooth grain characteristics whilst at the same time reducing friction and the possibility of tangling or ‘tie-ups’.

Equally important is the fact that TRUPOSOL WBF will not detrimentally influence the fogging values of the wet blue leather produced, as is the case with many other chrome-stable fatliquors.


Quantities to be used will vary on individual requirements, however, as a guide 0.5 - 1.5 %, based on limed split weight, will generally suffice.

TRUPOSOL WBF should be prepared for use by adding it to 4 - 5 times its own volume of water at 30 - 35 °C with stirring. The addition of the prepared fatliquor emulsion to the pickle float should be made at the start of the process and in accordance with the temperature required.

Safety and storage

When handling TRUPOSOL WBF, normal safety precautions associated with the handling of chemicals should be observed. For more specific details please refer to our safety data sheets.

TRUPOSOL WBF can be stored for up to one year, if temperatures below 5 °C and above    40 °C can be avoided. On prolonged storage or extremes of temperature TRUPOSOL WBF may exhibit some settlement which can be rectified by either warming and/or stirring the product thoroughly before use.
