Abstract

1394647 Electro-depositing bright zinc OXY METAL FINISHING CORP 16 April 1973 [5 Jan 1973] 18264/73 Heading C7B An aqueous alkaline, preferably cyanide-free Zn electro-plating bath contains alkali metal zincate and as brightener a quaternary ammonium compound which is the reaction product of a polyalkylene imine and an organic ammonium halide having a halogen which reacts with the N of the imine. The zincate may be present as 5-50 g/l ZnO and 50-250 g/l NaOH; 0.5-50 g/l of the brightener may be present. The bath may contain as further brighteners: 0À005-10 g/l of a N - containing heterocyclic compound, e.g. 2-amino or 2-mercaptobenzothiazole as described in Specification 1387529; 0À005-5 g/l of a pyridine compound, e.g. a betaine of benzylchloridenicotonic acid or methyl (or ethyl) nicotinate of benzylchloride (or allyl bromide) quaternary; anisaldehyde (bisulphite), glue, polyvinyl alcohol or glycerol ester thereof, gelatine, peptone; and/or as chelating agents nitrilotriacetic acid or E.D.T.A. or alkali metal (e.g. Na) salts thereof. The organic ammonium halide may be produced by reacting a tertiary amine, e.g. trimethyl, triethyl, tributyl, tridecyl, tribenzyl or triphenyl amine, with epichlorohydria in presence of hypochlorous acid. The substrate may be steel.
