Properties:

TRUPOTAN VS is a combination tanning agent intended for the retanning of all types of leathers, but is especially suitable for the production of chrome-free upholstery leathers and car upholstery leathers.

With TRUPOTAN VS a well-filled, fine grained leather with a round handle is obtained.

TRUPOTAN VS brings about a dye levelling without reducing the colour value. 

TRUPOTAN VS is very suitable for the production of leathers with low free formaldehyde content.

Application:

The quantity of TRUPOTAN VS to be applied will depend upon the type of leather required.
When used in the tanning process of pre-tanned wet white, 15 - 20 % TRUPOTAN VS, based on shaved weight, will normally suffice to produce excellent fullness and handle.
Application can be made in two additions at intervals of 60 minutes.

When used in the retanning of wet blue, shoe or upholstery leather, quantities between 5 and 15 %, based upon shaved weight, will normally suffice to improve fullness and handle.

In order to avoid iron stains from contaminated water or shaving, it is recommendable to utilise small quantities of sequestering agent such as RESISTOL® FEL in the process.


Safety and storage:

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

TRUPOTAN VS
can be stored for up to 18 months, if kept in a dry place.
