Poptan FR6

Molecule Structure Image



Poptan FR6 is an anionic neutral syntan based on nitrogen containing resin (melamine syntan) for retannage of all types of chrome leathers. It precipitates under acid conditions and this precipitate, in combination with colloidal and other softening agents, has a selective filling action which improves the more open structured areas of the leather. When used as a retannage for neutralized chrome stock results in a leather with a full fell, a tight flexible grain and uniform softness.
