Titre : Decomposable crosslinking paint : Waste minimization Type de document : texte imprimé Auteurs : Y. Nakayama, Auteur Année de publication : 2000 Article en page(s) : p. 57-62 Note générale : Bibliogr.

The method was studied to minimize the waste produced by the elimination of the decomposable paint film. This was performed in two steps: a dipping in aqueous solution containing solvents and acids, and a successive wash with solvents. Decomposition of the crosslinking bonds and the elution of the decomposed free crosslinker took place in the first dipping process, and the elimination of the decomposed resins in the second washing process. The aqueous solution could be used for a long time without contamination by the decomposed resins, and the decomposed resin could easily be recovered from the resin solution containing no other contaminants.

Titre : Life cycle environmental assessment of paint processes Type de document : texte imprimé Auteurs : Stella Papasavva, Auteur ; Sheila Kia, Auteur ; Joseph Claya, Auteur ; Raymond Gunther, Auteur Année de publication : 2002 Article en page(s) : p. 65-76 Note générale : Bibliogr. Langues : Américain (ame) Tags : Cycle vie (environnement) Déchet industriel solide Pollution air eau Consommation énergie Emission polluant Prévention pollution Protection environnement Peinturage Index. décimale : 667.9 Revêtements et enduits Résumé : The environmental impact of three different automotive paint scenarios: (a) solventborne primer-waterborne basecoat-solventborne clearcoat, (b) powder primer-waterborne basecoat-solventborne clearcoat, and (c) powder primer-waterborne basecoat-powder clearcoat were investigated. Scenarios (a) and (b) are in production by the U.S. automotive industry and scenario (c) is a potential future goal. The scenarios modeled assume a greenfield plant, considering a mid-size sport utility vehicle that is painted in two separate colors. A complete life cycle analysis of the materials and processes was carried out using commercial state-of-art software. The analysis showed that a transition from solvent-based to powder-based coatings for the primer and clearcoat leads to an improvement in the environmental performance of the paint processes. The decrease in total energy consumption, water usage, and sludge generation is 22%, 34%, and 27%, respectively. The paint scenario comprised of powder primer-waterborne basecoat-powder clearcoat will minimize the environmental impacts of the painting processes for all the metrics examined in this study.
