… 2-yl)amino]benzenesulphonate compared to glutaraldehyde and Cr(III) salts. As a chrome-free tanning agent, it eliminates the risk of generating carcinogenic Cr(VI). Another project demonstrated the application benefits of a resin structurally similar to melamine resins. This polymer, synthesized through aromatic nucleophilic substitution of triazine derivatives—rather than traditional condensation of melamine with formaldehyde —eliminates free melamine and formaldehyde in both products and leather, while enhancing retanning performance …
