Titre : Get to (very) hydrophobic surfaces Type de document : texte imprimé Auteurs : Dietmar Appelhans, Auteur ; Michaela Genan-Smolka, Auteur ; Dieter Lehmann, Auteur Année de publication : 2004 Article en page(s) : p. 24-31 Note générale : Bibliogr. Langues : Anglais (eng) Index. décimale : 667.9 Revêtements et enduits Résumé : Powder coatings - Dirt-repelling and self-cleaning powder coating surfaces are interesting for many applications (e.g. road signs, architectural use, cars). In order to realize permanent surface properties a choice of fluorinated (Rf-) components were used to synthesize special types of resins and crosslinkers. The investigations were carried out using polyurethane binders based upon a polyester-resin and an uretdione crosslinker. Best results of water advancing contact angles were in the range from 120° to 150°. The deciding explanation for the realization of very hydrophobic surface properties is the defined formation of heterogeneous surfaces in conjunction with only few nm high pillars on the top of the surface.

Titre : Modifying the surface Type de document : texte imprimé Auteurs : Yaoxing Han, Auteur ; Xinsheng Ma, Auteur ; Hongming Cao, Auteur ; Jianding Chen, Auteur ; Qiufang Wu, Auteur Année de publication : 2004 Article en page(s) : p. 38-39 Note générale : Bibliogr. Langues : Anglais (eng) Tags : 'Revêtement acrylate' 'Polyméthyl méthacrylate' 'Oxyde de fer jaune' 'Pigment dispersion' Goethite Index. décimale : 667.9 Revêtements et enduits Résumé : Iron oxide yellow - Based on the research findings of interfacial characteristics of goethile (alpha-FeOOH, iron oxide yellow), a method was developped to modify the surfaces of alpha-FeOOH pigments via in-situ polymerization pf methyl methacrylate in aqueous slurry. The scanning electron micrographs indicate that the polymethyl methacrylate anchors on the surfaces of the particle homogeneously. Polymer treated a-FeOOH particles can be easily dispersed in organic medium to form a stable colloid and have an imporoved heat resistance. The modified pigment dispersion in acrylate coatings gives a stable viscosity after storage. Permalink : https://e-campus.itech.fr/pmb/opac_css/index.php?lvl=notice_display&id=9380

[article]
Titre : Benefits of UV-curable coatings Type de document : texte imprimé Auteurs : Kevin Bruen, Auteur ; Kurt Davidson, Auteur ; Daniel F. E. Sydes, Auteur ; Peter M. Siemens, Auteur Année de publication : 2004 Article en page(s) : p. 42-48 Langues : Anglais (eng) Index. décimale : 667.9 Revêtements et enduits Résumé : Typically flexible fluoropolymer PUR coatings are spray applied directly after vulcanisation of the rubber during the continuous extrusion process and then thermally cured in a series of conventional, microwave or infrared ovens. This conventional cure process is costly, inefficient and results in high overhead costs. In the age of continual demands for cost reduction, improved efficiency and reduction in VOC levels, a range of waterborne 1-pack UV curable coatings meeting market and technical requirements have been developed. Realizing the benefits of a UV curable coating system in a continual extrusion process means at least an enormous increase in speed of cure, waste reduction, lower solvent emissions, lower energy costs and huge space savings. In some cases it is even the only way to implement the application of a coating into to the manufacturing process due to limitations in line speed and/or in the mechanical properties of the rubber substrate. Note de contenu : Before the curing step the coating has no abrasion or chemical resistance and is often tacky
UV-curable coating systems cure in less than a second
UV-technology for continuous extrusion processes coating systems
Space saving
Easy installation of UV curing equipment
Lower energy costs
Reduced waste
Increased line speed
Coatings are based on different types of waterborne PUR-dispersions
UV-curing equipment with very stable UV output over life time
Parameters tested: solvent resistance, abrasion resistance and flexibility
Water removal stage is essential
Combining UV-output of a V- and a D-bulb respectively of a H and a D-bulb results in superior solvent resistance.Permalink : https://e-campus.itech.fr/pmb/opac_css/index.php?lvl=notice_display&id=9445

Titre : More than the sum of its parts : ECJ "trouble shooter" series keeps track of faults and helps to rectify flaws Type de document : texte imprimé Année de publication : 2004 Article en page(s) : p. 58-59 Langues : Anglais (eng) Index. décimale : 667.9 Revêtements et enduits Résumé : Even tiny faults whilst formulating, producing or processing coatings can have expensive consequences. Coatings formulators, producers and users should know about potential sources of faults and how to prevent them and rectify them in order to achieve optimal quality as well as to work efficiently and cost-effectively. This edition sees the beginning of the new "Faultless" series which deals with possible faults and describes faults as well as presenting their possible causes, remedies and measures to prevent them. Note de contenu : Small faults can easily lead to bigger ones
