Es wird gezeigt, daβ Hydrazinhydrochlorid die Oxydation des Sn(II) wirksam unterdrückt; zusammen mit Gelatinehydrolysat läβt sich mit diesen Zusätzen eine hohe Einebnung (bis zu 100%) der Zinnoberfläche erzielen.(3) Auf Grund der mitgeteilten Untersuchungsergebnisse wird ein hochleistungsfähiger Pyrophosphatelektrolyt zur elektrolytischen Verzinnung und Blechverzinnung empfohlen.
