From EIS and corrosion potential data analysis it was found that (1) there is not a significant influence of the tannin pretreatment on the anticorrosive protection level, which depends particularly on the barrier effect afforded by the applied paint system (however, as the corrosion process starts, tannins may cause the repassivation of steel); (2) the enhancement of the protection level afforded by the tannin primer was restricted to short immersion periods and corrosive media that were not very aggressive; and (3) water uptake was not significantly affected by the presence of the tannin primer.

Système de pulvérisation (technologie)Index. décimale : 667.9 Revêtements et enduits Résumé : The short drying times of spray paints are of great benefit in some applications, and this property allows for painting over almost immediately. However, this fast-drying process precludes following it using conventional techniques. In a previous article, we used the dynamic speckle to follow the drying process of solvent-based and water-based paints with relatively long drying times, and recently we developed alternative speckle contrast methods to characterize faster processes. This article presents the application of these methods using dynamic speckle techniques to study the drying of a spray paint. Activity image display is also included.

Titre : Formulation and testing of a waterborne primer containing chestnut tannin Type de document : texte imprimé Auteurs : O. Pardini, Auteur ; Javier I. Amalvy, Auteur ; A. R. di Sarli, Auteur ; R. Romagnoli, Auteur ; V. F. Vetere, Auteur Année de publication : 2001 Article en page(s) : p. 99-106 Note générale : Bibliogr. Langues : Américain (ame) Tags : Matériau revêtement Peinture eau émulsion anticorrosion primaire réactive Formulation Inhibiteur corrosion Tanin Phosphorique acide Acier Essai brouillard salin vieillissement accéléré Protection Etude expérimentale Acrylique dérivé polymère Index. décimale : 667.9 Revêtements et enduits Résumé : The development of a water-based pretreatment system containing chestnut tannin and phosphoric acid and the assessment of its anticorrosive properties through different conventional tests are discussed in this work. Treated steel panels coated with different paint systems were subjected to standardized (salt spray, humidity chamber, adhesion, and flexibility) and electrochemical (corrosion potential, EIS) tests. Electrochemical tests were performed by employing only panels coated with the wash primer to determine its protective effect. The binder employed in this research was prepared in the laboratory by emulsion polymerization of acrylic monomers. It was found that the tested formulation protected steel against corrosion by forming ferric tannate, which prevented oxide formation. After performing the salt spray tests, it was observed that no oxide spots developed on the scratch mark although some blisters were detected. The good stability of the binder in low pH media (pH: 2.0-2.5) and the binder/substrate interaction are decisive factors in the performance of this aqueous pretreatment system.
