NOVELTY - The method comprises applying a pressure-sensitive adhesive mass (5) based on isobutylene block copolymers to and/or around the areas of an electronic arrangement (1) to be encapsulated. The adhesive mass is provided in the form of adhesive tape. The adhesive mass and/or the areas of the electronic arrangement to be encapsulated are heated before, during and/or after the application of the adhesive mass. The adhesive mass is cross-linked after the application to the electronic arrangement. The application of the adhesive mass takes place without subsequent hardening.    USE - Method for encapsulating an electronic arrangement against permeates, where the electronic arrangement are electrophoretic or electrochromic structure or displays, organic or polymeric light emitting diodes in display devices or as lighting called electroluminescent lamps, light-emitting electrochemical cells, organic solar cells such as dye and polymer solar cells and thin-film solar cells on the basis of silicon, germanium, copper, indium and selenium, organic field effect transistors, organic switching elements, organic optical amplifiers, organic diodes, organic or inorganic sensors, or organic or inorganic based radio frequency identification transponders.    ADVANTAGE - The method is capable of easily, rapidly and simply encapsulating the electronic arrangement against the permeates with good cohesive and adhesive properties, high flexibility, good barrier properties against oxygen, good resistance to UV-radiation and various chemicals, high shear and peel strength, aging resistance and high transparency thus continuously and effectively manufacturing the electronic arrangement with improved shelf life and high performance.    DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for an electronic arrangement.    DESCRIPTION OF DRAWING(S) - The diagram shows a schematic view of a first optoelectronic arrangement.
