Spectroscopie d'impédance électrochimiqueIndex. décimale : 667.9 Revêtements et enduits Résumé : Anticorrosion primers and direct-to-metal (DTM)-coatings are protective coatings with a primary function of protecting against corrosion. A secondary purpose is to maintain the aesthetic aspects and value of expensive good such as cars, trucks and aeroplanes. The cost of corrosion runs to approximately 3-4 % of GDP on an annual basis and therefore has an global economic impact of around US$3.3 billion.

PolyamidesUn polyamide est un polymère contenant des fonctions amides -C(=O)-NH- résultant d'une réaction de polycondensation entre les fonctions acide carboxylique et amine.
Selon la composition de leur chaîne squelettique, les polyamides sont classés en aliphatiques, semi-aromatiques et aromatiques. Selon le type d'unités répétitives, les polyamides peuvent être des homopolymères ou des copolymères.

TopographieIndex. décimale : 667.9 Revêtements et enduits Résumé : Achieving Class A appearance over fiber-reinforced substrates can be challenging. We discuss the evolving measurements used to characterize topcoated surface appearance. The influence of carbon fiber on the surface appearance of a thermoplastic resin-transfer-molding (RTM) substrate is related to differences in thermal expansion within the substrate.
The mechanism identified here is then extended to several chopped-fiber-filled thermoplastic substrates where the fiber-mapping effect is manifested in a different manner. We then investigate the influence of thick-film applications to the Class A surface on appearance. Our analysis finds that both the depth and the width or wavelength of the substrate affect the ability of the thick films to cover fiber mapping.Note de contenu : - Class a appearance defined and measured

Traîtements de surfaceIndex. décimale : 667.9 Revêtements et enduits Résumé : In general, the term ‘industrial finishing' refers to the process of painting a product in a factory environment. The paint process at the end of a production line is arguably as important as the design of the product itself, because the coating system not only sells the product by its appearance, but is typically fundamental to the product's useful lifetime.
No matter what the product to be coated is, the design of the finishing process has to consider three phases : surface preparation, the application of any surface treatment and the application of the coating(s) coupled with the appropriate drying/curing process.Note de contenu : - Surface preparation and surface treatment
