Pickling and Tanning - Hint 3

Environmental concerns oblige the tanner to ensure that chrome-tanning liquors are fully utilised, with as little as possible entering the waste stream. This has been studied by TFL, with resulting auxiliaries being made available to ensure 'high exhaustion' of the chrome baths.

To increase the efficiency of the fixation chrome special agents may be used in the tannage to provide additional reactive sites for chrome uptake. MAGNOPAL TGR is an acrylic agent for use in chroming to improve dispersion and chrome exhaustion.
