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

Terpolymère styrène anhydride maléïqueIndex. décimale : 667.9 Revêtements et enduits Résumé : We directly measured the local composition profiles in phase-separating photocurable thin films using confocal Raman spectroscopy. To avoid light scattering at phase interfaces, we developed a novel technique to replace the solvent with a monomer to match the reflective indices in the cured films. The results indicated that the concentration distribution of the polymer was uniform in solvent-free monomer/initiator binary solutions, while it was spatially nonuniform when the solvent-based films were thermodynamically unstable and promoted reaction-induced phase separation upon UV irradiation on the top surface. In the latter case, the film exhibited a dual-layer structure, in which the polymer concentration was almost uniform near the top surface, while concentration gradients developed near the bottom surface. The thickness of the top layer with a uniform concentration profile increased with the increase in the UV light intensity. These results implied that the propagation of the reaction front and the resulting light-driven transport of the solvent toward the bottom coating layer played key roles in the formation of nonuniform concentration profiles in photocuring solution coatings.

Revêtements organiquesIndex. décimale : 667.9 Revêtements et enduits Résumé : When the surface is exposed to atmospheric influences it is observed that the main damage factors are corrosion and carbonation, it is sufficient to cover the surface with cernentitious slurries for protecting concrete structures, facades and building interiors as well as minera) substrates. The cementations slurries helping to reduce the concrete carbonation process.
To ensure long lasting durability, the exposure condition on a structure has an influential role on its durability. Decision to use or not a protective coating shall be taken after thorough consideration by selecting different types of coating system based on different polymers, Portland cernent and many other additives.Note de contenu : - Corrosion inhibitors (for reinforcement)

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.

Revêtements organiquesIndex. décimale : 667.6 Peintures Résumé : The basic process of film coalescence has been described frequently in the conservation and paint industry literature, though technologists acknowledge the over-simplification of this model and the need for further research. Acrylic emulsions are composed of particles of amorphous polymer suspended in water. The two-phased system is held in suspension by surfactants and/or other surface stabilisers. During drying, water evaporates to draw the spherical polymer particles Gloser, which then meld together to form a 'honeycomb' network. A coalescing-solvent additive ensures that the polymer particles remain malleable during — and after— this process, to produce more complete compaction, even after the water has evaporated. Eventually, the boundaries between particles become barely detectable and the film is considered continuous. However, it has been shown that pores or micro-voids are often left within the film, readily seen with light microscopy and SEM. minimum film formation temperature (MFT), modulus of elasticity and viscosity of the resin, as well as the function of additives such as coalescing agents. Paints left to dry slightly below their Tg and MFT wi II result in films of h igher porosity. A paint drying significantly below its Tg will form a loose, powdery layer.
