Influence of surface chemical composition on UV-varnish absorption into permeable pigment-coated paper / Maiju Pykönen in Industrial & engineering chemistry research, Vol. 49 N° 5 (Mars 2010) 

Public ISBD [article]  in Industrial & engineering chemistry research > Vol. 49 N° 5 (Mars 2010) . - pp. 2169–2175 Titre : Influence of surface chemical composition on UV-varnish absorption into permeable pigment-coated paper Type de document : texte imprimé Auteurs : Maiju Pykönen, Auteur ; Kenth Johansson, Auteur ; Roger Bollstrom, Auteur Année de publication : 2010 Article en page(s) : pp. 2169–2175 Note générale : Industrial Chemistry Langues : Anglais (eng) Mots-clés : Chemical  composition;  UV-Varnish;  Permeable;  Hydrocarbon  plasma Résumé : Fluorocarbon, organosilicon, and hydrocarbon plasma coatings were used to modify the surface of permeable pigment-coated paper, and their impact on UV-varnish absorption was investigated. According to mercury porosimetry results, the plasma coatings had no influence on the porous structure of the paper. X-ray photoelectron spectroscopy (XPS) and time-of-flight secondary ion mass spectrometry (ToF-SIMS) results showed characteristic surface chemical compositions for each plasma coating. The fluorocarbon plasma coating increased the UV-varnish contact angles significantly, whereas the hydrocarbon plasma coating had no clear influence. When the UV varnish was applied with a flexography unit including nip pressure, the role of surface chemical composition seemed to become minimal. The viscosity of the UV varnish was shown to impact the absorption rate with and without external pressure. Note de contenu : Bibliogr.
