Langues : Anglais (eng) Index. décimale : 667.9 Revêtements et enduits Résumé : Micaceous iron oxide (MIO) is wide-spread in protctive coating due to its outstanding anticorrosive properties. A less obvious is using of MIO as a replacement of zinc dust in zinc rich primers. It follows from testing single layer coatings and paint systems at two corrosive environments that a partial replacement of spherical zinc dust by micaceous iron oxide influenced positively the adhesion of paints after the exposition at corrosive cabinets. The use of miscaceous iron oxide at the formulation of zinc rich primers is advantageous from ecological and also from prices reasons. Note de contenu : Building a shield of overlapping flakes / MIO pigments reduce formulation cost / Primers based on a combination of spherical zinc dust and IO / MIO enhanced mechanical properties of cured paints / Primer with pvc 65% resistant to salt spray (fog) test / Best result with half and half combination in humidity cabinet / Good adhesion with MIO En ligne : https://drive.google.com/file/d/1oZNBnIEHLM6-mAPs3rvy_zGXDDTNms-o/view?usp=drive [...] Format de la ressource électronique : Pdf Permalink : https://e-campus.itech.fr/pmb/opac_css/index.php?lvl=notice_display&id=9488 [article]

Spherical and lamellar zinc dust / Libuse Hochmannova in EUROPEAN COATINGS JOURNAL (ECJ), N° 3/02 (03/2002)  

[article]  inEUROPEAN COATINGS JOURNAL (ECJ) > N° 3/02 (03/2002) . - p. 36-41 Titre : Spherical and lamellar zinc dust Type de document : texte imprimé Auteurs : Libuse Hochmannova, Auteur Année de publication : 2002 Article en page(s) : p. 36-41 Note générale : Bibliogr. Langues : Anglais (eng) Index. décimale : 667.9 Revêtements et enduits Résumé : Zinc dust has been used as a high quality pigment for corrosion protection in primer coatings for steel for many years. Two types of zinc particles are produced: spherical and lamellar. Both, alone and in combination, have different influence on the viscosity behaviour, drying time, impact resistance and anticorrosive effect of a paint. This study shows the differences and that the combination of 1/3 spherical and 2/3 lamellar zinc dust have shown the best anticorrosive effect. Note de contenu : - Zinc coatings are porous - Zinc primer with CPVC for electric conductivity - Primer with a combination of spherical and lamellar zinc dust - Viscosity of primers with spherical zinc dust increases with higher PVC - Particle shape is important for coatings properties - Lamellar shape reduces drying time and improves impact resistance - Panels preparation for anticorrosive tests - Combination of spherical and lamellar zinc dust improves result of salt spray (fog) test - Good results in humidity cabinet - Good adhesion with lamellar zinc dust En ligne : https://drive.google.com/file/d/1cSStjiBmWQfb02eBMzufjESLxd9PU8AN/view?usp=drive [...] Format de la ressource électronique : Pdf Permalink : https://e-campus.itech.fr/pmb/opac_css/index.php?lvl=notice_display&id=10871 [article]
