TRUPOTAN GSX has been developed for tanning all kinds of leathers and skins whenever stand or spring is required

TRUPOTAN GSX is not easily soluble in water but can be added in powder to the drum. TRUPOTAN GSX fills and compacts the leather during the tanning process, giving fullness and mellowness to the grain.

TRUPOTAN GSX can be combined to resin or vegetal retanning agents.

Leathers retanned with TRUPOTAN GSX show a light stand.

Uses

TRUPOTAN GSX is specially suited for the retanning of sheep or goatskins for shoe and lining.

To retan heavy, chrome retanned leathers, we suggest using TRUPOTAN GSX together with resin or vegetal tanning agents.
