Sheih, Auteur Année de publication : 1994 Article en page(s) : p. 41-45 Note générale : Bibliogr. Langues : Américain (ame) Tags : 'Peinture eau' Liant 'Epoxyde résine' Feuil 'Propriété mécanique' Flexibilité Utilisation Bidon Index. décimale : 667.9 Revêtements et enduits Résumé : New two-piece can technologies are increasing market demand for more flexible can coatings. In response to the demand, several different waterborne epoxy resin systems have been prepared by synthesizing epoxy resin with new flexible backbones and converting them to onium forms. More specifically, the coating epoxy resins were made by modifying the resin backbone with extended aliphatic spacers of either bisphenol or diepoxide structures. These flexible epoxy resins were then converted to onium forms by reacting the epoxide group with an aqueous mixture of lactic acid and nicotinamide. When the resulting aqueous dispersions are formulated and cured with melamine-formaldehyde resin, the resultant coatings exhibit improved flexibility and pasteurization resistance as compared to coatings from high molecular weight diglycidyl ether of bisphenol A epoxy resin controls. The new epoxy resin backbone chemistry, waterborne conversion chemistry, and coating properties are described in this paper.

Titre : Odour emission to atmosphere from two-piece beer and beverage can manufacturing plants Type de document : texte imprimé Auteurs : J. W. Casper, Auteur ; R. P. Redman, Auteur Année de publication : 1995 Article en page(s) : p. 210-216 Note générale : Bibliogr. Langues : Anglais (eng) Tags : 'Emission polluant' Odeur 'Usine fabrication' Bidon Laquage 'Composé volatil' 'Pollution air' organique' Index. décimale : 667.9 Revêtements et enduits Résumé : Most industrialised nations have now enacted environmental protection regulations primarily aimed at reducing the volatile organic compounds ( VOC ) emitted to atmosphere. Whilst there may be little obvious immediate benefit of their implementation to those living in the neighbourhood of VOC emitting factories, what does make an immediate impact is odour emission and particulary any changes in odour.
The UK Environmental Protection Act requires that the aim should be that all emissions are free from offensive odour outside the process boundary , as perceived by the local authority Inspector'.
This paper is concerned with the emissions to atmosphere, and in particular odour emissions, from the lacquering processes associated with two-piece beer and beverage can manufacture. Despite steady progress in VOC reduction from such processes by the adoption of water-borne lacquer systems, odour nuisance complaints do occur from time to time.
In this paper we estimate the magnitude of the VOC and odour problem using know parameters of the lacquering process and then compare this with experimentally determined odour measurements of actual lacquers.Note de contenu : - THE LACQUERING PROCESSES : Coater application - Basecoat stoving - Printer application - Rim varnish and / or overprint varnish application - Printer bake - Interior spray application - Interior bake
