ViscositéIndex. décimale : 667.9 Revêtements et enduits Résumé : Acetylenic based surfactants have long found utility in compliant coatings such as waterborne systems and are demonstrated here to enhance performance of solventborne high solids systems. Three new additives are shown to reduce surface defects such as craters and orange peel in conventionally spray applied polyester and epoxy paints. Important to this new additive technology is the lack of adverse effect on physical properties, recoatability, and durability of the applied coating. Also discussed are the theory and background of the origins of surface defects with emphasis on the influence of additives on paint rheology, compatibility, and surface tension.

VernisIndex. décimale : 667.9 Revêtements et enduits Résumé : Defects in transparent, solvent-free vinyl ether, and allyl ether maleate-functional coatings have been studied using conventional optical microscopy, scanning electron microscopy, atomic force microscopy, scanning acoustic microscopy, and confocal laser microscopy. Vinyl ether films with different curing rates and allyl ether films with different crosslink densities were prepared, and the number and appearance of defects present in the films were compared. The varying curing rates were achieved by using different initiators, whereas the changes in crosslink density were obtained by using monomers with different functionalities. Defects, such as craters and surface crumpling, were observed. Higher curing rates and increased crosslink densities were both found to promote the formation of defects. Atomic force microscopy, scanning acoustic microscopy, and confocal laser microscopy proved to be useful techniques in the characterization of organic coatings, with the latter being particularly well suited for viewing the interior of transparent coatings.

Polyacétate de vinyleIndex. décimale : 667.9 Revêtements et enduits Résumé : In the field of organic and printed electronics (e.g., polymer solar cells, OLEDs, or Li-ion batteries), there is a growing demand for thin functional layers with highly homogeneous surface topology. If these layers are coated from the liquid phase, the coating and drying steps affect the surface quality. As a result of inhomogeneous drying rates, the solvent concentration can vary along the top surface and the thickness of a solidifying solution, leading to local differences in surface tension. In turn, Marangoni convection, as the balancing mechanism, can occur and cause surface inhomogeneity. The in situ reconstruction of the free surface during drying has been presented elsewhere. During this investigation phenomena occurred that could not be completely understood without knowledge of the respective flow field. In the present work, the visualization of the flow field in thin polymer films [methanol-poly(vinyl acetate) solution with 67 wt% methanol] due to inhomogeneous drying is presented. To resolve the flow field, we apply fluorescent particle tracking (µPTV). Since both measurement techniques cannot easily be applied at the same time, the boundary conditions were adapted to the way of observation of each experimental setup. In the case of the setup for surface reconstruction of the free surface, locally different evaporation rates were realized by drying on a structured substrate (varying material). To force similar variation of the drying conditions in the case of the µPTV setup, the drying film was partially covered. As expected, both boundary conditions result in a propagating wave front towards regions of high surface tension. Combining both experimental setups, we were able to visualize the free surface and the flow structures up- and downstream of the wave front and found different flow regimes.

Revêtements -- Défauts:Peinture -- DéfautsIndex. décimale : 667.9 Revêtements et enduits Résumé : A paint film cross-sectioning technique has been developed which allows simultaneous characterization of a paint defect and the underlying substrate and pretreatment. The advantages of the technique include speed, accuracy of cross-sectioning the defect, simplicity, lack of polishing artifacts, and a pseudo-three-dimensional perspective which uniquely reveals the relationship between the defect, paint film and substrate. Disadvantages include possible damage to the sample or removal of contaminants by the solvents used. The prepared sample may be examined using an optical or scanning electron microscope (SEM), and analyzed by x-ray fluorescence (XRF) or other methods. The technique has proven especially useful for pinpointing the cause of defects resulting from interaction of the substrate or pretreatment with the paint film.
