ABSTRACT:
Aqueous, acid zinc electroplating solutions and method for electroplating zinc coatings are provided. The plating solutions of the invention contain a source of zinc ions, an electrolyte, at least one organic acid or salt thereof, and a novel grain-refining agent comprising a substituted polyhydric alcohol having three or more ethoxylated and/or propoxylated hydroxyl groups. Bright and lustrous zinc coatings can be electroplated from such solutions at temperatures ranging from between about 50.degree. to 100.degree. F., with the plating solutions exhibiting no significant cloud point.
