SolidesIndex. décimale : 667.9 Revêtements et enduits Résumé : Computer simulation of the random close packing of hard pigment particles and deformable latex particles in acrylic latex paint systems is described. The simulation requires only the particle size distribution of the pigment, the particle size distribution of the latex, and the deformation or softness of the latex. If these data are known, the packing density can be determined from the simulation. If paints with a range of pigment volume concentrations (PVC) are simulated, the critical PVC can be predicted from plots of packing density against PVC. The predicted values are in good agreement with experiment. Permalink : https://e-campus.itech.fr/pmb/opac_css/index.php?lvl=notice_display&id=18573

Revêtements en phase aqueuse:Peinture en phase aqueuseIndex. décimale : 667.9 Revêtements et enduits Résumé : Waterborne coatings are multi-component, heterogeneous systems containing a variety of additives, in addition to water, polymer binders, and pigment particles. The distribution of various ingredients in the coating films directly affects a coating’s appearance and performance ; for example, optical properties, substrate adhesion, chemical resistance, and mechanical durability. Over the years, a plethora of analytical tools have been utilized in coatings characterization and defect identification. Microscopy and vibrational spectroscopy are complementary techniques and the combination of the two can provide the most complete information regarding the distributions of different coatings ingredients, as well as the fate and the impact of liquids or particulates that come into contact with the dried coating films.

Revêtements organiquesIndex. décimale : 667.9 Revêtements et enduits Résumé : Acrylic emulsion artists' paints were received with much fanfare and excitement in the 1950s and 1960s. They embodied the characteristics that many artists had been searching for at that time, affording a means of expression that was distinct from oi I painting and its associated history and traditions. As described it, 'there was an urge to loosen painting. [These colours] released new kinds of tactile qualities'. These synthetic paints produced films of great clarity and phenomenal elasticity, were easy to manipulate, could be painted directly onto supports, dried quickly, were thinned with water and exhibited high resistance to ultraviolet degradation. It was changed to acrylics for a number of reasons. They dry faster, which they do, and that they retain their original colour, which they do.The durability and light and the fact that one can use water instead of turpentine : all that makes it easier given the abstract image. As painting needed less and less drying time, depth, and so forth, the materials came along that made that more obvious. In spite of their outstanding mechanical and aging properties, acrylic emulsion paintings do suffer damage, often through external influences. Within the conservation profession, concerns were soon raised as some of these newly painted works began to require cleaning and repair.

ViscoélasticitéIndex. décimale : 667.9 Revêtements et enduits Résumé : The location of hydroxyl functionality was investigated for thermosetting acrylic latexes. Large and small latex particles with and without hydroxyl functionality were also synthesized and characterized. Large and small latex particles with and without hydroxyl functionality were blended together, and the latexes were crosslinked. The location of hydroxyl groups in the small or large latex particles had an effect upon the thermomechanical properties and hence on the ultimate performance of the crosslinked latexes. The packing of the large and small latexes was dependent on small-to-large particle ratio, and in addition had an effect upon the speed of film formation. The higher concentration of hydroxyl groups in the small latex particles contributed more to the tensile properties of the latexes than the functionality of the large particles.
