Titre : New primary standard for specular gloss measurements Type de document : texte imprimé Auteurs : Maria E. Nadal, Auteur ; E. Ambler Thompson, Auteur Année de publication : 2000 Article en page(s) : p. 61-66 Note générale : Bibliogr. Langues : Américain (ame) Tags : Revêtement Peinture Propriété optique Feuil Brillant Méthode mesure Normalisation Index. décimale : 667.9 Revêtements et enduits Résumé : A new primary specular gloss standard has been developed at the National Institute of Standards and Technology to overcome the disadvantages of black glass. This new standard is a high-purity BaK50 glass with good mechanicaldurability and homogeneity. In addition, the index of refraction nD = 1.5677 is close to the
value specified for the theoretical standard, and the dispersion characteristics are similar to black glass.En ligne : http://www.google.fr/url?sa=t&rct=j&q=&esrc=s&source=web&cd=1&ved=0CDEQFjAA&url= [...] Format de la ressource électronique : Permalink : https://e-campus.itech.fr/pmb/opac_css/index.php?lvl=notice_display&id=5585

Titre : UV curing of aqueous polyurethane acrylate dispersions. A comparative study by real-time FTIR spectroscopy and pilot scale curing Type de document : texte imprimé Auteurs : Armin Tauber, Auteur ; Tom Scherzer, Auteur ; Reiner Mehnert, Auteur Année de publication : 2000 Article en page(s) : p. 51-60 Note générale : Bibliogr. Langues : Américain (ame) Tags : Revêtement Peinture eau Durcissement Rayonnement UV Dispersion aqueuse Uréthanne polymère Acrylate Spectrométrie IR Transformation Fourier Temps réel Echelle pilote Etude comparative Photoamorceur expérimentale Index. décimale : 667.9 Revêtements et enduits Résumé : Real-time FTIR spectroscopy was used to study the chemical and physical factors, e.g., photoinitiator and temperature, affecting the UV curing of dried films from aqueous polyurethane acrylate dispersions. Poor conversion of the acrylate double bonds (67%) observed at room temperature can be overcome by irradiation at elevated temperatures. At 353 K almost complete conversion is observed, even with reduced photoinitiator content. Single or multiple UV-light flash experiments were performed to simulate technical parameters, e.g., cure speed and number of required UV lamps, with the help of RTIR spectroscopy. The results obtained were confirmed by pilot-scale UV curing experiments: one or, at most, two UV lamps of high intensity are sufficient for the curing process with respect to the double-bond conversion. The coatings based on the polyurethane acrylate dispersion show low sensitivity towards oxygen from air. Moreover, in comparison to UV curing under inert nitrogen atmosphere, a small positive effect on the conversion in the presence of air has been observed, which might be due to the contribution of peroxyl radicals or their decomposition products to curing.

Titre : Preparation of reversible thermochromic building coatings and their properties Type de document : texte imprimé Auteurs : Yiping Ma, Auteur ; Beirong Zhu, Auteur ; Keru WU, Auteur Année de publication : 2000 Article en page(s) : p. 67-71 Note générale : Bibliogr. Langues : Américain (ame) Tags : Revêtement Bâtiment Peinture Thermochromisme Formulation Colorant Microencapsulation Propriété optique Etude expérimentale thermosensible Index. décimale : 667.9 Revêtements et enduits Résumé : Thermochromic dyes reversible at normal ambient temperatures have been identified and microencapsulated using an emulsion polymerization process. By blending microencapsulated thermochromic dyes and nonthermochromic pigments with ordinary building coatings, thermochromic building coatings, in which colors change reversibly from warm tones to cool tones at about 18°C have been obtained. The application and performance properties of the coatings were measured, and it was found that adding thermochromic dyes did not degrade the properties of coatings. The aging results showed that the aging properties of the coatings were not ideal; the reasons will be given in another paper.

Titre : New anti-corrosive painting technologies at the beginning of the 21st century Type de document : texte imprimé Auteurs : E. Almeida, Auteur Année de publication : 2000 Article en page(s) : p. 73-84 Note générale : Bibliogr. Langues : Américain (ame) Tags : Matériau revêtement Peinture anticorrosion Protection corrosion Peinturage Acier galvanisé haute teneur solide poudre eau photodurcissable radiodurcissable Préparation surface Passivation Phosphatation Utilisation Article synthèse Index. décimale : 667.9 Revêtements et enduits Résumé : The aim of this work is to provide a general overview of current trends in anti-corrosive painting technologies for steel and galvanized steel substrates. After some considerations of important aspects inherent to the environment and humans and to competitiveness and quality, a of new painting technologies is given, in particular solvent-free liquid paints, powder paints, water-based paints, and radiation-cured paints. As a complement to this, mention is made of specific aspects concerning galvanized steel and application technologies, such as cataphoresis and autophoresis. Finally, some references are presented concerning the short- and mid-term future of anti- corrosive painting technologies.
