Titre : Electrokinetic : Properties of combined alkyd-acrylic dispersions Type de document : texte imprimé Auteurs : Olga A. Kulikova, Auteur ; Eugeny A. Indeikin, Auteur ; Vladimir B. Manerov, Auteur ; Natalija B. Skopintseva, Auteur Année de publication : 2000 Article en page(s) : p. 32-35 Note générale : Bibliogr. Langues : Anglais (eng) Tags : Coating material;'Water base paint' 'Aqueous dispersion' 'Acrylic polymer' Emulsion Oligomer 'Alkyd resin' 'Electrical properties' 'Electrokinetic potential' 'Electrophoretic mobility' pH 'Particle size' Index. décimale : 667.9 Revêtements et enduits Résumé : Fast drying, high protective properties and adhesion to a lot of substrates can be provided by combined binders of thermoplastic polymer dispersions and alkyd oligomer emulsions. To assure their successful use it is essential to avoid deterioration of aggregate stability may be caused by different dispersion composition of combined dispersion phases, in all cases however the determining factor is electrokinetic property of dispersions. In this study the influence of dispersion phase particles, pH of dispersion medium of combined acrylic dispersions and alkyd emulsions stabilized with different types of surfactants on electrokinetic potential is shown. Note de contenu : - Characterization of an electric double layer
- Factors influencing the electrokinetic potential of dispersion phase particles
- ζ-potential of alkyd emulsions with different particle sizes is negative in a wide range of pH values
- ζ-potential increases when pH exceeds 7.0
- Light transmission is sharply decreased in incompatibility zonePermalink : https://e-campus.itech.fr/pmb/opac_css/index.php?lvl=notice_display&id=11015

Titre : Bring back the steel ? The growth of plastics in automotive applications Type de document : texte imprimé Auteurs : Rose Ann Ryntz, Auteur Année de publication : 2006 Article en page(s) : p. 3-14 Note générale : Bibliogr. Langues : Américain (ame) Tags : 'Flow agents' 'Dynamic mechanical properties' Fluorescence Hardness 'Scratch resistance' 'UV spectroscopy' Photodegradation Polyacrylics Isocyanates 'Melamine-formaldehyde resins' Photostabilizers Polyurethanes Solventborne 'UV, EB radiation cure' Waterborne 'Service life prediction' Weatherability Automotive-OEM High-solids Latex PARP Index. décimale : 667.9 Revêtements et enduits Résumé : The development of plastics has evolved from the use of natural materials to the use of chemically modified natural materials and, finally, to completely man-made molecules. Plastics continue to improve, to afford flexibility, high-impact, and strength. In automotive applications, plastics have increased in utilization to comprise approximately 10% of the total vehicle weight. They offer increased ductility, freedom from corrosion, and increased styling capability. Although plastics have had a remarkable impact on our culture, it is obvious that there is a price to be paid for their use. Plastics are almost too good, as they are durable when processed correctly, but easily damaged when utilized in the incorrect application. Plastics also degrade very slowly, making recycling mandatory. And finally, while plastics consume only 4% of the world's oil production (petroleum is the raw material that is chemically altered to form commercial plastics), their cost hinges on the cost of petroleum. As petroleum prices increase, so too will the cost of plastic. In 2004, the higher price of plastic forced many plastic manufacturers out of business, and forced many automotive suppliers to look into alternative replacements. With publications such as USA Today reporting that current oil reserves will only last 40 years, scientists continue to seek cheaper alternatives to plastic. This article summarizes the history of commercial plastic development, with a focus on utilization of the materials in automotive applications. Damage criteria of plastic components, namely scratch, oxidative degradation, and impact, are discussed in relation to coatings and processing robustness. Environmental regulations, particularly in relation to recycling mandates, are explained. And finally, trends in alternative material development, including bioplastics, films, ceramic coatings, and nano-composites, are formulated.
