Synthetic lamellar iron oxide: a new pigment for anticorrosive primers

Abstract

The need for environmentally acceptable anti‐corrosive pigments to replace those based on lead and chromates in priming paints has stimulated the emergence of phosphate, molybdate and borate types and many others. However there are widespread doubts about the ability of these “non‐toxic” alternatives to provide the same degree of corrosion‐resistance as the lead and chrome pigments. This has encouraged a search for ways and means of boosting the inhibitive action of the newer pigments, for instance by mixing with other ingredients that might promote a synergistic effect. There has been a growing interest in utilising inert “barrier” pigments for this purpose and the development of synthetic iron oxide with a flake‐like crystalline structure is a significant step forward in this context.
