ABSTRACT:
Surfactants made by the successive ethoxylation and propoxylation of diamines are effective in providing a fine-grain tin coating in high-speed strip-steel plating operations under conditions of high current density. Surfactants prepared by successive propoxylation and ethoxylation are also effective.
