Coatings update: Scientific studies 1977: Part 2

Abstract

Appleby and Mayne [Journal of the Oil & Colour Chemists' Association, 59, 2 (1976) p.69] have studied the relative protection provided by red lead to linseed oil, tung oil, oiticia oil and a long oil ,alkyd varnish. The degradation products have been identified by gas liquid chromatography, the corrosion properties on mild steel having been compared by partial immersion tests. Linseed oil proved to be the most protective material; oiticia oil was next and the alkyd last. The authors concluded that lead azelate formed in the linseed oil paint and had strong corrosion‐inhibiting properties. These same authors [British Corrosion Journal, 10, 4 (1975) p. 201] have studied the effect of cations on the auto‐oxidation of linseed oil fatty acids and the inhibitive properties of the degradation products. Again, they found that alkaline earth azelates might be useful corrosion‐inhibiting additives for non‐soap forming vehicles.
