In order to meet this demand, as one of the leading companies with chrome free tanning technology, Derui has developed SELLATANCFXliq This is a special fatty aldehyde tanning agent, which can make the pretanning of full thickness leather much easier than the glutaraldehyde pretanning agent currently used.

As a new solution for the pre tanning of wet white leather and vegetable tanned leather, Derui This innovative tanning agent was improved and the tanning process was simplified. Because of its masking effect, SELLATANCFXliq can easily penetrate into the entire cross section of leather and is the preferred pretanning agent for full thickness leather. In addition, it can also ensure that the water is easily squeezed out when the leather is squeezed, so that the subsequent thickness of the shaving can be more accurately controlled. Importantly, because of its extremely low convergence, it can give leather smooth, fine, compact grain and good dyeing performance.
