Replacement retanning Syntan
Due to the low astringency of GREIBOTAN GSH it is recommended in the production of aniline leathers. The grain won’t be overtanned and remains firm with closed and fine pores. GREIBOTAN GSH shows a good dispersing action on vegetable extracts. It improves their penetration and distribution on the leather surface and in depths and enhances the dyeability.
