Abstract

It is well known that iron oxide, a pigment widely used in the paint industry, can not bring about chemical inhibition of the corrosion process. This pigment, however, belongs to the semi‐conductor group and as such its structure is amenable to modification. The method essentially consists of mixing another oxide with iron oxide and subsequent calcination. The modified iron oxide was studied in four media viz., linseed oil, alkyd, chlorinated rubber and sodium silicate. The paints prepared in these media were evaluated by laboratory and natural weathering tests. The results have shown that the modified iron oxide pigment does bring about corrosion inhibition and that its performance is on a par with that of red lead in linseed oil and can be used with advantage. There is an overall saving in the cost of protection per unit area of iron and steel.
