METALLIC LEAD — PROTECTIVE MARINE PAINTS: An Evaluative Discussion

Pure metal lead in a very finely divided form has quite different electrochemical properties from lead in the massive state and is a paint pigment of exceptional rust‐inhibitive power. ‘Genuine’ metallic lead paints have been known for nearly 30 years, but only in the last decade has extensive practical use of ‘extended’ paints, in diverse environments, shown them to provide protection at least equal to that given by red lead.
