Abstract
As compared with other pigments, red lead has a decided protective value when applied as a paint to iron and steel surfaces. The vehicle of the paint interacts with the lead oxide, forming comparatively insoluble complex glycerates and basic lead soaps which cement the pigment particles together, strengthen the paint film and make it waterproof. The electrochemical interaction between the lead oxide and the metallic iron of the surface appears to be of secondary importance as far as rendering the iron resistant to rust is concerned. The insoluble lead compounds formed during ageing or storage of red lead paints are investigated at length.Keywords
