摘要： The invention relates to a slot coating die for applying a fluid composition on a substrate, comprising: an upstream die part (1) having a first face (5); a downstream die part (2) having a second face (7), the first face (5) of the upstream die part (1) facing and being parallel to the second face (7) of the downstream die part (2); wherein at least one of the upstream die part (1) and the downstream die part (2) comprises at least one fluid inlet (12) configured for making the fluid composition flow between the upstream die part (1) and the downstream die part (2), and wherein at least one of the upstream die part (1) and the downstream die part (2) comprises at least one horizontal channel (13) on the first face (5) or second face (6), wherein the horizontal channel (13) is at least partially blocked so that the fluid composition is prevented from flowing through at least part of the horizontal channel (13). The invention further relates to a method for applying a fluid composition on a substrate by using said slot coating die and the use of said slot coating die to reduce or prevent ghosting during a slot die coating process. The invention further relates to a method of restructuring an initial slot coating die for applying a fluid composition on a substrate.

摘要： The invention relates to a slot coating die for applying a fluid composition on a substrate, comprising: - an upstream die part (5) having a lower edge (9); - a downstream die part (6) having a lower edge (12), the downstream die part (6) facing the upstream die part (5) and spaced apart from the upstream die part (5), and the lower edge (9) of the upstream die part (5) being vertically aligned with the lower edge (12) of the downstream die part (6); - a patterned shim plate (7) between the upstream die part (5) and the downstream die part (6), the patterned shim plate (7) having a lower edge (16b), wherein the lower edge (16d) comprises at least one cut- out (17); and - a blank shim plate (1) having a lower edge (2b), said lower edge (2b) being devoid of cut-out, the blank shim plate (1) being located between the downstream die part (6) and the patterned shim plate (7); wherein at least one of the upstream die part (5) and the downstream die part (6) comprises at least one fluid inlet (15) configured for making the fluid composition flow between the upstream die part (5) and the downstream die part (6), and the at least one cut-out (17) is configured for dispensing the fluid composition on the substrate. The use of the blank shim plate (1) makes it possible to reduce or prevent drooling of the fluid composition.
