  • Patent number: 4251331
    Abstract: A brightening agent is provided for the electrodeposition of zinc from an aqueous acid plating bath. The brightening agent is composed of an alpha-amino aliphatic carboxylic acid, a nonionic surface active compound and a carbonyl compound. The brightening agent may be added to an electroplating bath containing zinc ions, chloride ions, and boric acid. The use of the brightening agent eliminates the use of ammonium chloride as a bath constituent, and unexpectedly produces bright electrodeposits at extremely high current densities.

  • Patent number: 4100040
    Abstract: A zinc brightener additive compises a polymeric amine selected from the class consisting of a linear aliphatic amine polymer, an aminated polyepichlorohydrin, a polyethylenimine, and combinations thereof, a propylene oxide-ethylene oxide block copolymer prepared by the sequential addition of propylenene oxide followed by ethylene oxide, or vice versa, to a residue of an organic compound containing active hydrogen atoms such as propylene glycol or an amine base, and an aliphatic ketone. Additionally, an aqueous acid electroplating bath containing the polymeric amine compound in combination with the propylene oxide-ethylene oxide block copolymer and an aliphatic ketone provides bright, lustous electrodepositions of zinc.
