The shape of things to come / Dawn Skinner in POLYMERS PAINT COLOUR JOURNAL - PPCJ, Vol. 192, N° 4454 (07/2002)

[article]  inPOLYMERS PAINT COLOUR JOURNAL - PPCJ > Vol. 192, N° 4454 (07/2002) . - p. 14-17 Titre : The shape of things to come Type de document : texte imprimé Auteurs : Dawn Skinner, Auteur Année de publication : 2002 Article en page(s) : p. 14-17 Langues : Anglais (eng) Catégories : Lampes à rayonnement ultraviolet Rayonnement ultraviolet -- Absorption Revêtements -- Séchage sous rayonnement ultraviolet:Peinture -- Séchage sous rayonnement ultraviolet Robots industriels Index. décimale : 667.9 Revêtements et enduits Résumé : The traditional markets for UV coatings often involve flat objects, such as printed matter and CDs, but curing on a 3D surface is more difficult. The author shows how to engineer solutions for complex shapes. For UV curing to continue to flourish and grow in terms of market share, it surely has to be successful in industrial coating applications. This will be a challenge for all those involved in the industry: raw material suppliers, formulators and UV equipment suppliers.

Cutting edge conference / R. Stephen Davidson in POLYMERS PAINT COLOUR JOURNAL - PPCJ, Vol. 192, N° 4454 (07/2002)

[article]  inPOLYMERS PAINT COLOUR JOURNAL - PPCJ > Vol. 192, N° 4454 (07/2002) . - p. 18-20 Titre : Cutting edge conference Type de document : texte imprimé Auteurs : R. Stephen Davidson, Auteur Année de publication : 2002 Article en page(s) : p. 18-20 Langues : Anglais (eng) Catégories : Additifs Encre Epoxydes Polyacryliques Produits chimiques -- Migration Revêtements -- Séchage sous rayonnement Revêtements -- Séchage sous rayonnement:Peinture -- Séchage sous rayonnement Revêtements en phase aqueuse Revêtements:Peinture Index. décimale : 667.9 Revêtements et enduits Résumé : Radtech 2002 proved to be popular event. The author reviews the best papers and concepts were put forward during the conference and exhibition. Just in case anyone was in any doubt as to the versatility of radiation curing, the 'End-user Product Showcase' featured a range of products, sports equipment, printed circuit boards, coated metallicised using plastics that were manufactured using the technology, and a Team UV car. This latter exhibit was used to draw attention to the fact that radiation curing is used in many varied ways in car production and listed 12 electrical and electronic applications, 5 head-lamp assembly applications, 7 graphics and identification applications, and 16 miscellaneous functional applications.

Inks for new markets / Kris Sime in POLYMERS PAINT COLOUR JOURNAL - PPCJ, Vol. 192, N° 4454 (07/2002)

[article]  inPOLYMERS PAINT COLOUR JOURNAL - PPCJ > Vol. 192, N° 4454 (07/2002) . - p. 21-22 Titre : Inks for new markets Type de document : texte imprimé Auteurs : Kris Sime, Auteur Année de publication : 2002 Article en page(s) : p. 21-22 Langues : Anglais (eng) Catégories : Encre Encre -- Séchage Formulation (Génie chimique) Index. décimale : 667.4 Encres Résumé : In June PPCJ, The author examined the potential markets for UV inks, and this month we explore how to formulate inks to meet the needs of new markets. The formulation of the ink relies heavily upon the end use requirement. A growth area is in the food packaging industry where solvent based inks are frowned upon due to the VOC's being present. There are several classes of ink grades from direct contact with the food, say printing onto eggs, all the way through to exterior packaging. Direct contact with the food obviously has the most stringent parameters to fulfill in terms of safety. Food packaging that will not come into direct contact with the food item has less stringent rules and much of the testing is done in house. Often, for historical reasons, an ink will be used with no testing, simply relying on the fact that it has 'always been used' and 'everybody else uses it'. Very little is understood about the possible migration of materials through food packaging, especially in the areas of uncured monomers. Several barrier layers are often employed to minimise this migration but long-term effects are only estimated, as information is often gathered through simulated accelerated age testing. Despite these issues UV curing inks are growing in usage because of their durability and gloss. Note de contenu : - Formulating with UV - Applications - Getting personal - Table : 1.

It's a growth industry / Sandy Morrison in POLYMERS PAINT COLOUR JOURNAL - PPCJ, Vol. 192, N° 4454 (07/2002)

[article]  inPOLYMERS PAINT COLOUR JOURNAL - PPCJ > Vol. 192, N° 4454 (07/2002) . - p. 23-24 Titre : It's a growth industry Type de document : texte imprimé Auteurs : Sandy Morrison, Auteur ; Ken Johns, Auteur Année de publication : 2002 Article en page(s) : p. 23-24 Langues : Anglais (eng) Catégories : Revêtements hygiéniques:Peinture hygiénique Index. décimale : 667.9 Revêtements et enduits Résumé : Although biocides are used to prevent bacterial growth, hygiene coatings are relatively new. The authors unravel the mysteries behind coatings specifically formulated to keep buildings free of micobial growth. Biocides are not the only way to control problems of microbiological contamination. In the emerging field of hygienic coatings, a range of novel technologies are converging to create surfaces which reduce contamination risks in food preparation areas, operating theatres and many other critiral zones. Our current lifestyles - fast foods, fast travel, air conditioning, combined with an ageing population - demand increased attention to minimising dangerous microbiological contamination. At the same time, antibiotic resistance is increasing and traditional methods of control through biocides and aggressive cleaners are coming under stricter regulation. Attention is now being increasingly paid to coatings specifically formulated to aid in the fight against bacterial and related contamination, known under the general term 'hygiene coatings'. Much of the technology required has been developed relatively recently and only a few coatings manufacturers are so far active in this field. However, the formation of a PRA 'coatings group' for hygienic coatings has attracted a geast deal of interest and the first major international conference on hygienic coatings is taking place this year in Brussels. PPCJ will be reporting on the event in the next issue.
