Titre : Pigment relevant aspects of colour measurement Type de document : texte imprimé Auteurs : Juan M. Oyarzun, Auteur Année de publication : 2000 Article en page(s) : p. 34-47 Note générale : Bibliogr. Langues : Anglais (eng) Index. décimale : 667.9 Revêtements et enduits Résumé : How does colour arise from a pigmented coating? After a concise treatment of the fundamental Kubelka-Munk theory, this article describes the principles of colour measurement, the determination of colour differences according to the CIE and ClElab colour systems, and the colorimetric characterisation of pigments. Application possibilities of colour measurement in pigment production and processing are outlined Note de contenu : - Black body radiation and colour temperature
- Relating absorption, scattering and reflection - Kubelka-Munk-theory
- Correction of the Kubelka-Munk equation
- Colour mixing and reflectance curves
- Geometries of reflectance measurements and their uses
- Colour perception - The CIE-system
- Defining lightness
- Easier measurements - the trichromatic method
- Metamerism - colour differences depend on light sources
- Determination of colour difference - the CIELab system

Titre : R & D -engine of growth or black hole ? Type de document : texte imprimé Auteurs : Ian F. Harrison, Auteur ; John E. Dunstone, Auteur Année de publication : 2000 Article en page(s) : p. 48-54 Note générale : Bibliogr. Langues : Anglais (eng) Index. décimale : 667.9 Revêtements et enduits Résumé : There are often two opposing views of Research & Development. One is that innovation translated into new and improved products is the key means by which a company can generate growth even in a low growth market such as coatings. The other view is that R&D is an expense and that 90% of this expense is unnecessery and sometimes technical self indulgence. Unfortunately for the latter view, it is difficult to know which 10% is necessary and studies seem to indicate strong benefits from R&D. Note de contenu : - Relating R&D to the market
- Steps to develop a new product stream
- Practical considerations

[article]
Titre : Superior coatings with alkyd and ketonic resin blends Type de document : texte imprimé Auteurs : Vilas D. Athawale, Auteur ; A. V. Chamankar, Auteur Année de publication : 2000 Article en page(s) : p. 57-64 Note générale : Bibliogr. Langues : Anglais (eng) Index. décimale : 667.9 Revêtements et enduits Résumé : Because of their low cost and good compatibility with a wide variety of other polymers, alkyd based coatings are used in a large variety of applications. However, to improve their performance, the alkyd resins can be blended with ketonic resins. Such blends were analysed by SEM, and tested for their shelf life. Improvements in properties such as drying time, hardness, adhesion, flexibility, gloss, skinning tendency, impact resistance and chemical resistance were studied. Note de contenu : - Blending to improve the performance of alkyds
- Preparation of the blends
- Simultaneous oxygen activation and solvent evaporation effect fast drying
- Improvement in hardness and gloss
- Increased adhesion
- Ketonic resins serve as stability additives
- Water resistance decreases with increasing ketonic concentration
- High impact resistance due to compatibilityPermalink : https://e-campus.itech.fr/pmb/opac_css/index.php?lvl=notice_display&id=11058

Titre : Pore blocking by corrosion products Type de document : texte imprimé Auteurs : G. Blustein, Auteur ; Beatriz del Amo, Auteur ; R. Romagnoli, Auteur Année de publication : 2000 Article en page(s) : p. 74-82 Note générale : Bibliogr. Langues : Anglais (eng) Index. décimale : 667.9 Revêtements et enduits Résumé : Many attempts have been made to improve the corrosion resistance of galvanised steel, such as alloys development and the employment of organic coatings, in the so called duplex system, to provide a barrier effect. The organic coating usually contain inhibitive pigments to enhance corrosion resistance of the system. In the present paper, the anticorrosive performance of a commercial duplex system was evaluated by accelerated and electrochemical tests. It was found that the exceptional properties of the tested paint system rested on the presence of an inhibitor in the primer and on the relatively low permeability of the topcoat which maintained a constant value during the whole test period. Note de contenu : EXPERIMENTAL : Electrochemical tests - Accelerated tests
RESULTS AND DISCUSSION : Electrochemical tests - Primed steel was more active in sodium sulphate and less active in sodium perchlorate solution - The primer cannot provide an important barrier effect - The topcoat was effective in resisting the aggression on both chloride and sulphate ions - Corrosion products blocked active sites and restrained corrosion - Accelerated testsPermalink : https://e-campus.itech.fr/pmb/opac_css/index.php?lvl=notice_display&id=11059
