Influence of extender type of performance of modified lamellar zinc primers / Carlos A. Giudice in JOURNAL OF COATINGS TECHNOLOGY AND RESEARCH, Vol. 1, N° 4 (10/2004)
[article]
Titre : Influence of extender type of performance of modified lamellar zinc primers Type de document : texte imprimé Auteurs : Carlos A. Giudice, Auteur ; A. M. Pereyra, Auteur ; J. C. Benitez, Auteur Année de publication : 2004 Article en page(s) : p. 291-304 Note générale : Bibliogr. Langues : Américain (ame) Tags : Etude expérimentale Peinture anticorrosion Résistance corrosion Relation formulation propriété Epoxyde résine Ester polymère Vinylique dérivé copolymère Caoutchouc chlore zinc primaire Protection Acier Index. décimale : 667.9 Revêtements et enduits Résumé : The objective of this work was to gain a deeper insight into the behavior of zinc primer, containing either lamellar zinc alone or lamellar zinc mixed with an extender by means of accelerated tests in salt spray (fog) chamber and a 100% relative humidity cabinet. Mica, kaolin, and synthetic calcium silicate were used as extenders. Several series of coatings were designed and manufactured employing the following binders: 20 cP chlorinated rubber, a vinyl copolymer, an unsaturated polymer, or an epoxy resin. A simultaneous analysis of the experimental data was performed taking into account that the best performance is attained at pigment volume concentration (PVC) values equal to or slightly lower than the critical one (CPVC). Results indicate that for every lamellar zinc primer, it is possible to select an extender of high oil absorption as the spacer of the zinc particles attaining both very good blistering resistance and anticorrosive performance.

Titre : Renewable rust inhibitors : Natural tannates can be effective anticorrosives for steel Type de document : texte imprimé Auteurs : A. M. Pereyra, Auteur ; Carlos A. Giudice, Auteur ; Juan G. Castano, Auteur ; Félix EcheverrÃa, Auteur ; L. K. Herrera, Auteur Année de publication : 2006 Article en page(s) : p. 24-28 Note générale : Bibliogr. Langues : Anglais (eng) Index. décimale : 667.9 Revêtements et enduits Résumé : Corrosion protection - Samples of tannins extracted from the quebracho colorado have been characterised and used both in pretreatment primers and, after conversion to metallic tannates, inn protective coatings. The variables which give best performance have been identified. It is shown that metallic tannates may be able to provide corrosion protection equal to that of toxic chromates.

Titre : Shaped for performance : The combination of lamellar zinc and mica improves the efficiency of zinc-rich primers. Type de document : texte imprimé Auteurs : A. M. Pereyra, Auteur ; Carlos A. Giudice, Auteur Année de publication : 2007 Article en page(s) : p. 40-45 Note générale : Bibliogr. Langues : Anglais (eng) Index. décimale : 667.9 Revêtements et enduits Résumé : Corrosion protection - Lamellar zinc was investigated as a partial or complete replacement for spherical zin in potassium-silate based zinc rich primmers.Additionaly, mica was examined as an extender for lamellar zinc.The best corrosion and blister resistance was obstained by using lamellar zinc combinated with mica, at zinc addition levels well bellow those normally required in such primers.

ZincIndex. décimale : 667.9 Revêtements et enduits Résumé : The objective of this work was to study the behaviour of zinc primers, containing either lamellar zinc alone or lamellar zinc mixed with an extender or with an extender/inhibitor mixture. Several formulations of coatings were designed. Accelerated tests were carried out by means of a salt-spray (fog) chamber and a 100% relative humidity cabinet. A statistical analysis was performed considering simultaneous ways of dry-film blistering resistance and anticorrosive behaviour. Results indicated that it was possible to incorporate an extender of high-oil absorption as a spacer of the lamellar zinc particles and also an inhibitor to improve the performance.
