Abstract:
A process for ascertaining the adhesive behavior of pressure-sensitive adhesive flat materials, comprising:applying said adhesive flat material to an elastic carrier film such that said adhesive flat material adheres to said elastic carrier film;enclosing said carrier film having said adhesive flat material adhered thereon in a test cell comprising an upper and a lower compartment having congruent edges, wherein said carrier film is interposed between an upper and a lower compartment of the test cell such that it lies within an internal chamber formed by both compartments of said test cell;subjecting said carrier film having said adhesive flat material adhered thereon to one or more mechanical stresses or repeated mechanical stresses; and,evaluating the degree of detachment of said adhesive flat material from said carrier film in response to said mechanical stress.
