EPIZOTAN FRN is soluble even in cold water and its solutions are compatible with acids, salts and chrome tanning agents. If used alone for tanning, it gives a white leather and in tanning wool skins, a comparatively pale leather is acheived without greening the wool. The consumption rate is about 2-3% in tanning (together with 5-6% chrome powder) and 2-4% in retanning (before neutralization).
