Neutralisation Tannin

short description:

The Neutralizing tannin is a specific synthetic tanning agent used in the leather re-tanning process. It is mainly applied in the neutralization process of chrome-tanned leather. Its core function is not simply to neutralize the alkali, but to moderately adjust the pH value of the leather blank through its buffering and restraining properties, while loosening the fibers and firming the surface texture, thus creating the best conditions for subsequent re-tanning, dyeing, and oiling.
