Abstract:
1. A multilayer coating method comprising: providing a first coating fluid; providing a second coating fluid, the second coating fluid having a surface tension that is greater than that of the first; moving a substrate along a path through a coating station; flowing the second coating fluid at a rate sufficient to form a continuous flowing layer towards the substrate; flowing the first coating fluid onto the continuous flowing layer thereby forming a composite flowing layer; subsequently contacting the substrate with the composite flowing layer such that the first coating fluid is interposed between the continuous flowing layer and the substrate; and forming the composite flowing layer into a film after the composite flowing layer contacts the substrate, the film comprising a first coating layer formed from the first coating fluid and a second coating layer formed from the second coating fluid, wherein the first coating layer comprises a continuous or a discontinuous layer.
