Abstract

The invention concerns an aqueous alkaline cyanide-free solution for use in the electrolytic deposition of lustrous and blister-free zinc or zinc-alloy coatings of uniform layer thickness on substrate surfaces. Electrolytic zinc- or zinc-alloy baths are used for depositing zinc or zinc-alloy coatings. The layers are partly decorative and for that reason the layers must have an even lustre across a wide current density range. However, sufficiently uniform layer thicknesses cannot be obtained on complex workpiece surfaces with sharp-edged structures and concave surface regions, and zinc and zinc-alloy layers deposited on such workpieces tend in addition to be more prone to blistering. These disadvantages are eliminated by a coating solution containing, in addition to the normal bath components, diallyl ammonium-sulphur dioxide copolymers of general structural formula (I) shown, and/or diallyldimethyl ammonium monomers.
