ABSTRACT:
Corrosion inhibiting particles comprise an inorganic oxide, particularly alumina, having corrosion inhibiting anions, particularly phosphate, chromate or benzoate anions, chemically bound to them. They may be prepared by contacting an oxide containing hydroxyl groups with an acidic solution containing the anions at ambient temperatures. The particles may be incorporated into protective coatings, e.g. paints based on epoxy resins, alkyd resins or chlorinated rubbers, in amounts up to 80% wt based on dry film weight, giving coatings with up to 4.0% corrosion inhibiting anions. Release of the anions is by ion-exchange with other anions e.g. the chloride anions of sea water or salt spray, and does not, as is normal with corrosion inhibiting coatings, depend on water solubility.
