POPTAN SDF is a light fast synthetic tanning agent for the use of both chrome and vegetable tanning . It is exceptionally stable to ultraviolet light , and in this respect it surpasses most other phenolic syntans.

The good dispersing effect of POPTAN SDF results in deeper and more uniform penetration of other retanning agents . It has a medium strong filling effect .
