Spectroscopie d'impédance électrochimiqueIndex. décimale : 667.9 Revêtements et enduits Résumé : The purpose of this investigation was focused on reducing the content of zinc phosphate in anticorrosive paints by means of the incorporation of low quantities of selected soluble corrosion inhibitors. The article describes the anticorrosive behavior of alkyd paints containing reduced levels of zinc phosphate, zinc oxide, and some soluble compounds used as additives (e.g., sodium polyphosphate, sodium phosphate, and sodium benzoate). Anticorrosive solventborne alkyd paints were formulated with a zinc phosphate content of 10% by volume (v/v) with respect to the total pigment concentration. In all cases, the PVC/CPVC (pigment volume concentration/critical pigment volume concentration) ratio was 0.8. Experimental paints, applied on sandblasted SAE 1010 panels, were evaluated by accelerated tests (salt spray cabinet) and electrochemical measurements (electrochemical impedance spectroscopy, EIS). The results show that the additions of small amounts of soluble corrosion inhibitors to low content zinc phosphate paint formulations enhance their performance in a very remarkable way. Perhaps, the most outstanding feature is that the employment of soluble additives allowed the reduction of the zinc phosphate content with concomitant savings.

Titre : Pore blocking by corrosion products Type de document : texte imprimé Auteurs : G. Blustein, Auteur ; Beatriz del Amo, Auteur ; R. Romagnoli, Auteur Année de publication : 2000 Article en page(s) : p. 74-82 Note générale : Bibliogr. Langues : Anglais (eng) Index. décimale : 667.9 Revêtements et enduits Résumé : Many attempts have been made to improve the corrosion resistance of galvanised steel, such as alloys development and the employment of organic coatings, in the so called duplex system, to provide a barrier effect. The organic coating usually contain inhibitive pigments to enhance corrosion resistance of the system. In the present paper, the anticorrosive performance of a commercial duplex system was evaluated by accelerated and electrochemical tests. It was found that the exceptional properties of the tested paint system rested on the presence of an inhibitor in the primer and on the relatively low permeability of the topcoat which maintained a constant value during the whole test period. Note de contenu : EXPERIMENTAL : Electrochemical tests - Accelerated tests
RESULTS AND DISCUSSION : Electrochemical tests - Primed steel was more active in sodium sulphate and less active in sodium perchlorate solution - The primer cannot provide an important barrier effect - The topcoat was effective in resisting the aggression on both chloride and sulphate ions - Corrosion products blocked active sites and restrained corrosion - Accelerated testsPermalink : https://e-campus.itech.fr/pmb/opac_css/index.php?lvl=notice_display&id=11059

Titre : Zinc hypophosphite : a suitable additive for anticorrosive paints to promote pigments synergism Type de document : texte imprimé Auteurs : C. Deyà , Auteur ; G. Blustein, Auteur ; R. Romagnoli, Auteur ; Beatriz del Amo, Auteur Année de publication : 2009 Article en page(s) : p. 369-376 Note générale : Bibliogr. Langues : Américain (ame) Tags : Anticorrosive paints Electrochemical tests Phosphate pigments Zinc hypophosphite Index. décimale : 667.9 Revêtements et enduits Résumé : In this investigation, the synergism promoted by zinc hypophosphite in an anticorrosive pigment mixture is reported. This paper describes the anticorrosive behavior of a commercial pigment mixture containing zinc hypophosphite, reduced levels of zinc phosphate, and zinc oxide. The anticorrosive performance of the pigment mixture was assessed by electrochemical techniques (corrosion potential and linear polarization measurements) employing pigment suspensions. The behavior of each separate component of the mixture was also studied in the same way. The nature of the protective layer was investigated by scanning electron microscopy (SEM). In a second stage, the anticorrosive properties of the pigment were assessed by incorporating it into alkyd and epoxy paints that were evaluated by accelerated (salt spray and humidity tests) and electrochemical measurements. Experimental results showed that improved anticorrosion protection is achieved in paints with reduced zinc phosphate contents as a consequence of the synergistic interaction between zinc hypophosphite and the other components of the pigment mixture.
