Wetting behavior of the shear thinning power law fluids ... The knowledge of the wetting characteristics of a coating solution is a prerequisite of assuring the final quality of thin films manufactured by the slot die coating process. Because the maximum coating speed is limited by defects, such as air entrainment, which are directly related to film quality, an understanding of the coating limits is ... The Mechanism of Air Entrainment in the Slot Die Coating ... slot die casting process at different operating conditions, in the past. However, few studies exist focusing on the investigation of the air engulfment phenomenon, especially for relatively high viscosity shear thinning materials. The mechanism by which air entrains in the domain has been studied numerically and

Slot Die Coating Technology - Paper, Film & Foil Converter Slot die coating systems can transcend limitations of conventional roll coating. Slot die coating emerges as an efficient, controllable alternative to roll coating and other conventional methods of applying fluids to web substrates. For a wide range of adhesives and low-viscosity coatings, today’s market and regulatory forces place a high ... Comparison of vertical and horizontal slot die coatings ... As shown in Fig. 8, when the solution viscosity is increased further to [mu] = 75 mPa s, the differences between the vertical and horizontal slot die coatings become very small, with the minimum wet thicknesses obtained for vertical coating marginally thicker than those for horizontal coating over the same range of coating speed. Precision Slot Die - mirwecfilm.com In the past decade, slot die has become one of the most widely used coating methods in the world. While the majority of slot dies on the market require time-consuming bolt adjustments to obtain uniformity, the precision of the Yasui Seiki slot die is due to meticulous in-house machining, to the 1/1000th of a millimeter to guarantee coating accuracy.
