Aromatic sulfonic acid condensate
In the retanning process of leather, it can disperse and dissolve the phytochemical tannin and its retanning materials in the bath, so that it can penetrate into the leather gently and evenly, which will effectively reduce the retanning material on the leather grain. The astringency improves the flatness of the leather grain surface and the elasticity of the leather body, which also contributes to more uniform dyeing.
