TRUPOTAN RKB when used on chrome-tanned side leather has excellent filling characteristics along with a smooth, flat grain. TRUPOTAN RKB exhibits little tendancy to bleach or lighten the shade of anionic dyeings.

On upholstery and bag leathers intended for milling, TRUPOTAN RKB can be used to advantage to help provide an even grain break. It is also possible to temper the handle of TRUPOTAN RKB by using it together with a replacement syntan, for example TRUPOTAN GR.

TRUPOTAN RKB can be used either during the later stages of neutralisation or in a fresh bath after neutralisation.
