Effect of nano-Al2O3 particles on the corrosion behavior of alkyd based waterborne coatings / Shailesh K. Dhoke in JOURNAL OF COATINGS TECHNOLOGY AND RESEARCH, Vol. 6, N° 3 (09/2009)  

[article]  inJOURNAL OF COATINGS TECHNOLOGY AND RESEARCH > Vol. 6, N° 3 (09/2009) . - p.353-368 Titre : Effect of nano-Al2O3 particles on the corrosion behavior of alkyd based waterborne coatings Type de document : texte imprimé Auteurs : Shailesh K. Dhoke, Auteur ; T. Jai Mangal Sinha, Auteur ; A. S. Khanna Année de publication : 2009 Article en page(s) : p.353-368 Note générale : Bibliogr. Langues : Américain (ame) Tags : Waterborne  coatings  Nano-Al2O3  Corrosion  resistance  UV Index. décimale : 667.9 Revêtements et enduits Résumé : A modification in the alkyd based waterborne coatings was studied with the addition of 0.05%, 0.1%, 0.2%, and 0.3% nano-Al2O3. Corrosion performance of the nano-composite coatings were evaluated by applying these nanocomposites on mild steel substrate and exposing them to salt spray, humidity, and accelerated weathering. Mechanical properties were studied by subjecting the coating to scratch and abrasion test. The results showed that, with an increase in the concentration of nano-Al2O3 there was an improvement in the corrosion resistance, UV resistance, and mechanical properties of the coatings indicating the positive effect of addition of nano-Al2O3 particles in the coatings. Further, the transparency of the coating was not altered, maintaining the optical clarity of the coating.

High performance waterborne coatings using nanotechnology / Shailesh K. Dhoke in PAINTINDIA, Vol. LIX, N° 8 (08/2009)

[article]  inPAINTINDIA > Vol. LIX, N° 8 (08/2009) . - p. 105-112 Titre : High performance waterborne coatings using nanotechnology Type de document : texte imprimé Auteurs : Shailesh K. Dhoke, Auteur ; A. S. Khanna, Auteur Année de publication : 2009 Article en page(s) : p. 105-112 Note générale : Bibiogr. Langues : Anglais (eng) Catégories : Anticorrosifs Nanoparticules Revêtements en phase aqueuse:Peinture en phase aqueuse Index. décimale : 667.9 Revêtements et enduits Résumé : High performance coatings : A low molecular weight, alkyd-based waterborne anticorrosive coating was formulated with resin : cross-linker ration of 70:30. The coating was modified with nano-Zn0 particles as pigments in different concentration (0.0.1 %, 0.02 % and 0.03 % by weight) to form a nano-composite coating. The nano-Zn0 modified composite coatings were applied on mild steel substrate by dipping. The coated panels were subjected to various test environments like salt spray, humidity and UV-weathering. The improvements in electrochemical performance of the composite coatings were evaluated using various analytical techniques like scanning electron microscopy (SEM) and electrochemical impedance spectroscopy (EIS). The result showed that, with increase in the concentration of nano-Zn0 there was an improvement in the corrosion resistance and UV resistance of the coatings indicating the positive effect of addition of nano-Zn0 particles to the coatings.
