Abstract
A non-cyanide zinc electroplating bath containing an effective brightening and leveling amount of a leveling and brightening agent comprising a bath soluble butyl nicotinate sulfate or sulfonated quaternary salt. The electroplating bath may further advantageously incorporate an effective brightening amount of a polyether compound as a supporting brightening agent and an effective leveling amount of methane sulfonic acid and salts thereof as a supporting leveling agent. The improved leveling of the bright electrodeposited zinc plate in accordance with the process aspects is attained over a relatively broad range of pH from about 2.0 to 7.5, and current density.
