In this study, the effect of curing process on simulated antisoiling properties of sol–gel coating was investigated. The sol–gel coating was spray-coated on pine sapwood and cured with different temperature and time combinations. The antisoiling properties were studied by measuring the water contact angle of the coating after different curing processes. In addition, abrasion resistance and contact angle of oleic acid were measured. An optical profilometer was used to investigate surface roughness of the coating. Sufficient hydro- and oleophobicity were obtained with all of the curing parameters. The comparison between curing parameters showed that lower temperature and 1–3 h curing time leads to significant improvement in the durability of the water and oil repellent properties of the coating.

Sol–gel based protective coatings for copper products / Juha Nikkola in JOURNAL OF COATINGS TECHNOLOGY AND RESEARCH, Vol. 5, N° 3 (09/2008)  

[article]  inJOURNAL OF COATINGS TECHNOLOGY AND RESEARCH > Vol. 5, N° 3 (09/2008) . - p. 335-344 Titre : Sol–gel based protective coatings for copper products Type de document : texte imprimé Auteurs : Juha Nikkola, Auteur ; Juha Mannila, Auteur ; Riitta Mahlberg, Auteur ; Jarmo Siivinen, Auteur ; Mika Kolari, Auteur ; Amar Mahiout, Auteur Année de publication : 2008 Article en page(s) : p. 335-344 Note générale : Bibliogr. Langues : Américain (ame) Catégories : Cuivre Métaux -- Revêtements protecteurs Sol-gel, Procédé Index. décimale : 667.9 Revêtements et enduits Résumé : Corrosion, fouling, and wearing of metal surfaces are the most common problems faced in industry as well as in environmental use. In the recent study, sol–gel based protective coatings were developed and deposited on different copper substrates. Different chemical pretreatments were used to enhance the adhesion and spreadability of coatings on copper surfaces. Substantial improvement of the corrosion resistance of sol–gel coated copper surfaces was obtained by a salt spray test. In addition, the sol–gel coatings increased hydrophobic and easy-to-clean properties of the copper surface. Variation of the curing temperature of the coatings caused changes in the morphology, adhesion, and topography of the sol–gel coatings. On the basis of the important information obtained in this study, the protective properties of sol–gel coatings can be tailored for copper and copper alloy substrates.
