TRUPOTAN MAF is the improved version of TRUPOTAN MAU and it does not contain any free formaldehyde.

It can be used on all leathers where filling and tightening is required.

TRUPOTAN MAF will not bleach anionic dyeings and can be used in conjunction with vegetable extracts and synthetic retanning materials.

In order to achieve optimum filling effect from TRUPOTAN MAF, it is preferred that the leather is first neutralised using a buffered syntan such as TRUPOTAN NGN before retannage . TRUPOTAN MAF can then be added to the exhausted retannage bath. Subsequent fatliquoring and dyeing can follow as required.

TRUPOTAN MAF can be added to the dye bath after acidification where it will impart an excellent grain tightening effect.

Trupotan MAF appearance can turn ,by ageing, from clear to slightly cloudy without affecting  at all its chemical behaviour and characteristics.

STORAGE STABILITY: TRUPOTAN MAF can be stored for up to twelve months, if temperatures below 5°C and above 35°C can be avoided. Drums should be kept sealed until use .By long storage it is possible that TRUPOTAN MAF will exhibit an increase in viscosity.
