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 ... Experimental Study on Air Entrainment in Slot Die Coating of High-Viscosity, Shear-Thinning Fluids - ScienceDirect 1. Introduction Many industrial processes involve applying coatings to a moving substrate for manufacturing thin films such as photographic, optical and energy functional films. Several coating processes exist for manufacturing thin films among which the slot die ... Wetting phenomena during processing of high-viscosity shear-thinning fluid - ScienceDirect Slot-die coating windows have been previously obtained by several researchers for low-viscosity solutions. However, practical applications necessitate the use of relatively high-viscosity (≫1 Pa s) non-Newtonian fluids for coating films. Also, earlier theoretical studies ...
