Gilded surfaces / Frank J. Maile in EUROPEAN COATINGS JOURNAL (ECJ), N° 12 (12/2022)  

[article]  inEUROPEAN COATINGS JOURNAL (ECJ) > N° 12 (12/2022) . - p. 26-31 Titre : Gilded surfaces : Innovative mixing system with effect pigments Type de document : texte imprimé Auteurs : Frank J. Maile, Auteur ; Adalbert Huber, Auteur ; Jiri Filip, Auteur Année de publication : 2022 Article en page(s) : p. 26-31 Note générale : Bibliogr. Langues : Anglais (eng) Catégories : Argent Colorimétrie Cuivre Effet doré Mélanges (chimie) Or Pigments à effets métalliques Pigments métalliques Index. décimale : 667.2 Colorants et pigments Résumé : Effect pigments based on ultra-thin pigment (UTP) technology can be used to create gold shades with exceptional hiding power and colour gamut for coating, printing and plastic applications. lnspired by the ternary plot known from the metal alloys Au-Ag-Cu, three UTP-based effect pigments (YY-YS-OO) have been mixed using the innovative Zenexo ternary system (ZTS) to imitate gold shades. This paper looks at the new system and the device used to characterise appearance of samples prepared using the ZTS approach. Laboratory processes can be simplified and significant costs saved by combining both innovations. Note de contenu : - Benefits of using ZTS - Easy mixing and processing - Wide range of applications - A new measuring device - Numerous tools available - A comparison of the ZTS applied to different applications - Coloristic evaluation of a selected colour shade - Flop, gloss, sparkle and graininess - Particle orientation En ligne : https://drive.google.com/file/d/1kyqhKMX3yptMP2M65afdCDjZWG91nF5K/view?usp=drive [...] Format de la ressource électronique : Pdf Permalink : https://e-campus.itech.fr/pmb/opac_css/index.php?lvl=notice_display&id=38528 [article]

Metallic pearlescent pigments for powder coatings / Cynthia A. Gosselin in COATINGS TECH, Vol. 19, N° 7 (08-09/2022)  

[article]  inCOATINGS TECH > Vol. 19, N° 7 (08-09/2022) . - p. 54-60 Titre : Metallic pearlescent pigments for powder coatings Type de document : texte imprimé Auteurs : Cynthia A. Gosselin, Auteur Année de publication : 2022 Article en page(s) : p. 54-60 Note générale : Bibliogr. Langues : Américain (ame) Catégories : Absorption Pigments à effets métalliques Pigments à effets spéciaux Pigments nacrés Revêtements poudre Index. décimale : 667.9 Revêtements et enduits Résumé : Color has a way of creating impact and enhancing spaces and objects. There is evidence all around us to suggest that people are drawn to colorful, shiny things. While color perceptions are subjective and deeply personal, there are some color and gloss effects that have universal meaning. Perhaps it is because many cultures have come to associate gloss with wealth, luxury, and beauty. Luminosity, iridescence, and holographic effects are a few of the ways that the love for metallic and pearlescent finishes has evolved. These additives enhance color by adding shimmer and brilliance, providing contrast and metamerism for the entire color palette. New technologies are making strong statements in all aspects of coatings and design, allowing colors to appear and disappear in light in a kaleidoscope of color displays and illumination across the entire color spectrum. The luminosity of metallic and pearlescent finishes stands out, immediately grabbing our attention. Specialized metallic and pearlescent pigments have been developed that allow coated surfaces to exhibit a more glamorous appearance, with luster and brilliance that sets them apart from finishes produced by using conventional pigments. Appliances, vehicles, cosmetics, printing inks, packaging, soaps, and even food and beverages are a few of the markets that have taken advantage of these additives to project beauty and command attention in a crowded world.
