Slot coating is commonly used in the manufacturing of adhesive and magnetic tapes, specialty papers, optical films, and many other products. In this process, the coating liquid is pumped to a coating die in which an elongated chamber distributes it across the width of a narrow slot through which the flow rate Low‐flow limit in slot coating: Theory and experiments ...

An experimental and analytical study on intermittent slot ... These technologies are often optimized empirically, since intermittent slot die coating is not mentioned in the scientific literature. In this work, we investigate the dominating and limiting mechanisms for intermittent slot die coating of non-Newtonian battery slurries.

In the Slot Die process, the coating is pressed out by gravity or under weight through a slot and onto the substrate. In the event that the coating is 100% solids, the process is termed "Extrusion" and for this situation, the line velocity is regularly much speedier than the rate of the extrusion. NUMERICAL SIMULATION OF VISCOELASTIC EFFECTS IN BLADE-OVER ... viscoelasticity of many coating liquids (Sullivan et al., 1987). The problem is compounded by the pres-ence of free surfaces, both upstream of the substrate and downstream of where the actual coating takes place (figure 1). Typically, for a Newtonian fluid, the coating thickness is one half the thickness of the Slot coating of mildly viscoelastic liquids - ScienceDirect In the present work, the low-flow limit of slot coating of mildly viscoelastic liquids is examined by solving the conservation equations for two-dimensional flow, coupled with either of two differential viscoelastic models that describe the mechanical behavior of dilute polymer solutions (namely the Oldroyd-B and FENE-CR models).
