Neuqin WF

The composition of Neuqin WF contains groups with a big complexing action. This allows to deeply neutralize the chrome tanned leather, moving the acids of the chrome-colagen complexes and buffering the acids that are being extracted. No over-neutralization of the leather is possible. Neuqin WF turns the non-fixed chrome into chrome complexes with tanning action. Neuqin WF does not create precipitation of chrome agents like other alkaline neutralizing agents. This asures the complete lack of chrome stains on the leather. The same way, it reduces the cationic charge of the leather, allowing a softer and evener entrance of the later added anionic products, giving a more equalized effect of the later dyes and more firmness and grain fineness. Its use not only does not bring free formaldehyde to the leather but also decreases noticeably the presence of formaldehyde in case it would be present.
