Langues : Anglais (eng) Catégories : Can coating Chromatographie en phase liquide à hautes performances Polyamines Qualité -- Contrôle Réticulation (polymérisation) Revêtements -- Aspect de l'environnement Index. décimale : 667.9 Revêtements et enduits Résumé : In the surface coatings industries, major advances have been made through the use of amino-formaldehyde-based resin technologies. The term amino resin refers to a group of viscous, thermosetting amino-group-containing components that have use in curing with other resins to form a cross-linked network. They are widely used as cross-linking agents for hydroxyl, carboxyl and amide functional polymers.

Effect of passivation treatment and storing on adhesion and protective properties of lacquered tinplate cans / J. M. Bastidas in JOURNAL OF COATINGS TECHNOLOGY (JCT), Vol. 69, N° 871 (08/1997)

[article]  inJOURNAL OF COATINGS TECHNOLOGY (JCT) > Vol. 69, N° 871 (08/1997) . - p. 67-75 Titre : Effect of passivation treatment and storing on adhesion and protective properties of lacquered tinplate cans Type de document : texte imprimé Auteurs : J.

Langues : Américain (ame) Catégories : Adhésion Aliments -- Emballages Anticorrosion Can coating Emballages métalliques Oxydes de chrome Passivité (Chimie) Vernis Index. décimale : 667.9 Revêtements et enduits Résumé : Tinplate cans internally coated with three commercial lacquer systems were studied. The relationship found between lacquer adhesion, metallic chromium (CrM), chromium oxide (CrOx), and total chromium (CrT) existing in the passivated layer was : adhesion=CrM+10 (CrOx/CrT). The study was completed by conducting electrochemical impedance spectroscopy (EIS) and direct current (DC) polarization experiments up to 410 days. A dilute acetic acid-sodium chloride solution was used as electrolytic and a full opened can was used as the working electrode and an electrolyte cell. Iron dissolution was determined by atomic absorption spectrophotometry (AAS). The EIS, DC, and AAS techniques gave similar results. Passivation treatment did not substantially affect the porosity results. Permalink : https://e-campus.itech.fr/pmb/opac_css/index.php?lvl=notice_display&id=18264 [article]

Electrochemical impedance spectroscopy as a tool for investigating the quality and performance of coated food cans / P. kern in JOURNAL OF COATINGS TECHNOLOGY (JCT), Vol. 71, N° 899 (12/1999)

[article]  inJOURNAL OF COATINGS TECHNOLOGY (JCT) > Vol. 71, N° 899 (12/1999) . - p. 67-74 Titre : Electrochemical impedance spectroscopy as a tool for investigating the quality and performance of coated food cans Type de document : texte imprimé Auteurs : P. kern, Auteur ; J. Lange, Auteur Année de publication : 1999 Article en page(s) : p. 67-74 Note générale : Bibliogr. Langues : Américain (ame) Catégories : Aliments -- Emballages Can coating Electrochimie Industries agro-alimentaires -- Emballages Qualité -- Contrôle Spectroscopie d'impédance électrochimique Vernis Index. décimale : 667.9 Revêtements et enduits Résumé : In the present work, electrochemical impedance spectroscopy (EIS) is explored as a tool for evaluating the quality of coatings on food cans. The properties of the coating-metal interface are evaluate using an equivalent electrical circuit representing intact and defect coating areas. The element corresponding to the charge transfer capacitance under pores, proportional to the wetted metal surface, is found to be the most useful element for quality evaluation. It is shown that with EIS, differences can be detected between new and filled cans from different suppliers, as well as between different product formulations. Three measurement techniques, i.e., initial state characterization, rapid dc aging and long-term electrolyte aging, are applied to a series of pet-food and beveroge cans, and the results compared with the performance of the same cans after filling and storage. It 15 shown that all three measurement techniques give basic guidance as to the long-term performance of the filled cans. However, the electrolyte-aging test was found to give the best precision in the performance prediction.
