CALCIUM PLUMBATE: A Post‐War Development in Anti‐Corrosive Paint Pigments

Abstract

Calcium plumbate constitutes an important and novel addition to the few existing rust‐inhibitive pigments for the protection of iron and steel. Like red lead it provides protection by a combination of basic and oxidising characteristics, as well as film‐forming properties by interaction with linseed oil. It is believed to passify both cathodic and anodic areas on iron and steel, and in this respect differs from other rust‐inhibitive pigments. In practice, it shows the behaviour which on theoretical grounds might be expected to be associated with this type of inhibition. Linseed oil paints based on calcium plumbate have been found to be remarkably free from any tendency to crack, and their adhesion on galvanised iron and timber suggests the value of suck paints as primers with a wide variety of applications.
