Apparatus and Method for Processing Shear Sensitive Coating Compositions

Abstract

The invention relates to a device for processing shear-sensitive coating compounds, with a transfer roller and a doctor blade, in particular a comma doctor blade, which are spaced apart from one another to form a coating nip, the device further having an outlet nozzle for dosing a coating compound, the outlet nozzle facing a lower nip opening of the coating nip with its nozzle opening, wherein the device comprises a forced conveying system via which a coating compound is dosed into the coating nip, the transfer roller and the doctor blade being arranged next to each other, so that the coating nip is permeable in the vertical direction (z), wherein the coating nip is between 30 and 400 μm and the outlet nozzle is an outlet of a rinsing chamber arranged below the coating nip. A corresponding method is also described.
