  • Patent number: 4405413
    Abstract: A bright acid zinc plating bath uses a surfactant or wetting agent having the general formula C.sub.n H.sub.2n+1 (OCH.sub.2 CH.sub.2).sub.x OCH.sub.2 COOH wherein n is either 8 or 9, and wherein between 30 and 70% of the surfactant contains between 17 and about 21 ethylene oxide groups and 70-30% contains between about 9 and about 12 ethylene oxide groups. When used with organic brighteners, the blend of surfactants permits the electrodeposition of a bright layer which resists the formation of haze or blush which can occur when a plated part is flexed or is subjected to elevated temperatures encountered, e.g., upon curing of a protective lacquer coating.
