Abstract
Phosphating bath for forming coatings on steel based on iron phosphates and contg. as main components alkali phosphates whereby minor additions of metal ions chosen from alkaline earth metals, Mn, Ni, Co, Al, Cr and Zn in amounts between 20ppm and the solubility limit are made to the bath. When used for undercoating of car bodies etc. beneath an electrophoretic paint layer, a more flexible, more adherent layer is obtained.
