Tannic acid - Wikipedia
WEBTannic acid is used in the conservation of ferrous (iron based) metal objects to passivate and inhibit corrosion. Tannic acid reacts with the corrosion products to form a more stable compound, thus preventing further corrosion from taking place.

Tannic Acid - an overview | ScienceDirect Topics
WEBTannic acid is a precipitative stabilizer extracted from gall nuts. With the chemical formula C76 H 52 0 46 it has a structure similar to that of other polyphenols. It works by making the ratio of polyphenols to proteins more even ( Siebert and Lynn, 1997 ). It is used as a specific precipitant of haze-active protein at a loading of 2–6 g/hl.

WEBDec 10, 2012 · Tannic acid is a specific tannin that formally contains 10 galloyl (3,4,5-trihydroxyphenyl) units surrounding a glucose center. Commercial tannic acid, however, consists of molecules with 2–12 galloyl moieties. Tannic acid contains no carboxyl groups, but is weakly acidic because of the multiplicity of phenolic hydroxyls.
