In the model coal tar components, naphthalene, quinoline, 2-naphthol, and phenanthrene showed good compatibility with polyurethane. To test their heavy duty anticorrosive properties, tensile adhesion strength of the cured coatings prepared with the compatible model coal tar components was measured, and the change in tensile adhesion strength as a function of time during salt-water spray treatment was measured. We found that the systems compounded with naphthalene, 2-naphthol, and phenanthrene showed good properties in an ordinary state for adhesion strength. However, only the system with 2-naphthol was found to have good properties in the change of tensile adhesion strength as a function of time during salt-water spray treatment. The curing time of the system with 2-naphthol was slower than that of the others, i.e., we found an inverse proportion between curing speed and adhesion durability. We also measured the dynamic viscoelasticity of cured coatings. We found that a tan delta curve of the system with 2-naphthol shifted towards a low temperature side and the tan delta at the temperature at which adhesion strength was measured was larger than that of the others. We hypothesized that the reason for the tan delta shift was a result of the decrease in crosslinking density because 2-naphthol partially capped the isocyanate group. Considering these results, we hypothesized that one of the reasons why the adhesion properties of the system with 2-naphthol had improved was due to the increase of tan delta.

Titre : Environmental issues in automotive coatings Type de document : texte imprimé Auteurs : V. S. Ram, Auteur Année de publication : 2001 Article en page(s) : p. 167-184 Langues : Anglais (eng) Tags : Asie Solvant 'Composé aromatique polycyclique' organique volatil' 'Protection environnement' 'Déchet industriel' 'Prévention pollution' 'Pollution air' 'Industrie automobile' peinture vernis' Inde Index. décimale : 667.9 Revêtements et enduits Résumé : Growing emphasis on a cleaner environment has led the paint industry to come up with new initiatives that reduce the environmental impact of automotive coatings. Technological advances have focused on reducing solvent emissions, cutting waste and eliminating toxic ingredients. Some of these technologies have been late entrants to India because of the prohibitive cost and the less stringent regulatory environment. However, the additional costs of environmentally sensible options are falling. Regulators are also likely to raise standards as automobile production goes up and the significance of the pollution load from the industry rises Indian automotive manufacturers too will, over time, move to options that were hitherto seeing a restricted use in our country.
