A high viscosity material is discharged in the form of a continuous thread from an application nozzle toward an end of a workpiece and a space S on the side of the workpiece so that the high viscosity material in the form of the thread adheres to a front surface of the workpiece and the high viscosity material discharged in the form of the thread into the space on the side of the workpiece pivots around an edge of the workpiece to a back surface of the workpiece and adheres to the back surface of the workpiece. The high viscosity material can thus be applied to both the front and back surfaces of the workpiece in one step of discharging the high viscosity material only from the front surface side of the workpiece.

Devices and methods for preparing a slurry for coating onto a substrate. The devices and methods of the present disclosure relate to providing a slurry in a closed volume with at least one passage. The slurry includes a solvent, a powder, and a binder. The slurry can also include a dispersion agent. The slurry is forced repeatedly under high pressure through the at least one passage in a first flow direction and then back through the at least one passage in a second flow direction, opposite the first flow direction. The forcing homogenously disperses the powder and the binder within the solvent. Both sides of the substrate are then coated simultaneously with the slurry extruded from the closed volume after the forcing. Curing of the coated slurry includes freeze drying to preserve the porosity of the slurry on the substrate.
