The graphics arts, printing and wood coating industries have already been successful in making the transition from classic solvent-based inks and coatings to UV curing, systems, where the change in state from liquid to solid is almost instantaneous as the UV curable material is passed at high speed through a drying system. As we move further into the 21st century, there is an ever-increasing demand for higher productivity and improved quality at reduced cost. Environmental concers also require that alternative processes be considered that use low odour, low toxicity chemistries that give no solvent emission and can be processed at high speed using more efficient lower energy systems. Both decorative and functional UV coatings are available which can give enhanced performance over that of conventional chemistries. In addition to surface protection, their use can also extend to silicone release coatings, pressure sensitive & structural adhesives and gasketing elastomers. New materials, such as UV powder coatings, are increase constantly emerging which can increase the scope over conventional finishing methods. Note de contenu : - Chemical variations - Lamp designs - Technological innovation - Powder and control - FIGURES : 1. New lamp designs, such as Aquacure, can be used on heat sensitive substrates. Cooling water is circulated through IR filters and cooled with a heat exchanger - 2. In a further development of Aquacure, the Monocure system (below) contains a single large diameter IR filter to create a compact unit - 3. Encapsulation or conformal UV coatings can be used in the electronics industry in a clean-room environments Permalink : https://e-campus.itech.fr/pmb/opac_css/index.php?lvl=notice_display&id=27967 [article]

Straight to glass / Harald Gavin in POLYMERS PAINT COLOUR JOURNAL - PPCJ, Vol. 192, N° 4458 (11/2002)

[article]  inPOLYMERS PAINT COLOUR JOURNAL - PPCJ > Vol. 192, N° 4458 (11/2002) . - p. 30-31 Titre : Straight to glass Type de document : texte imprimé Auteurs : Harald Gavin, Auteur Année de publication : 2002 Article en page(s) : p. 30-31 Langues : Anglais (eng) Catégories : Encre -- Séchage sous rayonnement ultraviolet Impression sur verre Traîtements de surface Index. décimale : 667.9 Revêtements et enduits Résumé : New surface treatment provides opportunities for glass decoration. The production of glass containers is growing. In 2001, the EU produced 17.82 million tons of glass containers - beverage bottles, food jars, and containers for pharmaceutics and cosmetics. Germany accounted for a quarter of the EU output and this equates to 17,622 million containers. Germany's production grew by 0.6% (100 million containers!) compared with the previous year's production. Marketers of premium beverages and of cosmetics prefer to promote their brands through the visiul impact of screen printed images on their containers and glass containers convey a quality image. Direct screen printing on glass is favoured when an upscale image is required as the durability of directly screen printed images will generally be better than that of adhesive labels. Cosmetic companies demand sophisticated bottle decorations to differentiate their brands from the competition. Multi-colour decoration with extremely tight colour to colour registration has to create an appealing package when fairly standard shaped containers are used.
