Method and device for the application of at least two chemically different flowing media

摘要

The invention relates to a process for applying at least two chemically different, flowable media, particularly solutions of polymers, dispersions or combinations thereof as adhesives, coating materials or coatings. By means of a multiple cascade die 1 at least two chemically different, flowable media 30, 32 are applied to web-form substrates 20; 40, 41 continuously in one operation. The total amount within a multilayer application 51 is between 2 g per m² to 200 g per m². The ratio of the individual layers 31, 33 within the multilayer application 51 to one another is between 0.1 to 100.
