    Shoe Upper Leather Tanning Agent

    At present, the demand for chrome free tannage in the tannery industry is increasing, not only in automobile leather, but also in shoe leather and leather leather.

    To meet this demand, Derry has developed SELLATANCFXliq as one of the leading companies with chrome free tanning technology.

    This is a special kind of fatty aldehyde tanning agent. It can make the pre tanning of full thickness leather much easier than the glutaraldehyde pre tanning agent currently used.


    As a brand-new solution for pre tanning of white wet leather and vegetable tanned leather, Derry improved this innovative tanning agent and simplified tanning process.

    Because of its function of restriction, SELLATANCFXliq can permeate the entire cross section of leather easily, and is the preferred pre tanning agent for full thickness skin.

    Moreover, it can also ensure that the water is easily squeezed out when the leather is being squeezed, so that the subsequent thickness of the shaving can be controlled more accurately.

    Importantly, because of its very low astringency, it can give leather a smooth, meticulous and compact grain with good dyeing properties.


    SELLATANCFXliq is stable for electrolytes, and can improve the shrinkage temperature of leather when used for pickling.

    Because of this, it can be used for chrome tanning or chrome retanning to improve the softness of leather and reduce the use of chromium powder.


    In SELLATANCFXliq, the content of free phenol and formaldehyde is very small, so it can be used to produce environment-friendly leather that can be passed through TFLWhiteLine standard.
