Coating shrinkage upon drying is a phenomenon well known to the paper coating industry where it often causes changes in the final structure of the coating layer, leading to poor results in terms of gloss, light scattering, surface strength, coverage and printability. The aim of this paper is to improve the understanding of coating shrinkage by measuring the forces related to the capillarity, ac...

Development of effective electrical magnetohydrodynamic (MHD) coating insulating induced current path is one of key fusion technologies for fusion blanket research and development. Electrical insulation coating is extremely important for lead lithium (PbLi) MHD thermofluid study from pointview of secure electric insulating wall condition. The alumina (Al2O3) coatings fabricated by a sol-gel met...

The effect of Co–P-CNT coating on the magnetic properties of grain oriented electrical steel was investigated. To analyse the coating, Raman spectroscopy, Superconducting QUantum Interference Device (SQUID), single strip testing, Scanning Electron Microscopy (SEM) and talysurf surface profilometry were performed. Raman spectra showed the D and G band which corroborates the presence of Multi-Wal...

Terahertz pulsed imaging (TPI) is a recent and nondestructive technique to quantify coating thickness of pharmaceutical tablet film coatings. In this study, TPI is used for the first time to quantify the progress of an active coating process. The dosage form consisted of a push-pull osmotic system comprising a two-layer tablet core with a functional film coating and a laser drilled hole. On top...

Opadry® II 1 Influence of Film Coating Process Parameters on the Gloss of Tablets Coated with Pigmented Aqueous Film Coating Formulations PURPOSE A common practice for enhancing the gloss of coated tablets is the application of a clear top-coat after applying a pigmented coating layer. In a recent study, substantial increases in tablet gloss were achieved using this multiple step approach.1 It ...

Optical fibers are drawn with resin coatings that protect the glass. In general UV-curable resins are used for the coatings, and in most single-mode (SM) fibers a dualcoating structure is adopted. Each coating layer has an independent function in the protection of the glass. The coating in direct contact with the glass is known as the primary (P) coating, with the role of acting as a buffer aga...

Print quality demands for coated papers are steadily growing, and achieving coating uniformity is crucial for high image sharpness, colour fidelity, and print uniformity. Coating uniformity may be divided into two scales: coating thickness uniformity and coating microstructure uniformity, the latter of which includes pigment, pore and binder distributions within the coating layer. This thesis c...

The purpose of this study was to investigate coating process of tablets with the novel starch hydrolysate emulsion. The process was performed manually in a coating pan rotating 35 rpm, with a stream of dry air (40 - 45 degrees C). The coated tablets were of fairly good quality. A total tablet surface was calculated for evaluation of quantity of starch hydrolysate emulsion for one step of coatin...

The progressive replacement of organic solvent-based coatings by waterborne latex polymer coatings has substantially renovated the coating industry, and generated huge environmental and health benefits. Today, on top of the continuing demand for higher performance and lower costs, the coating industry faces tighter regulation and higher sustainability standards. In addition, the new waterborne ...
