Presented is a heat-activatedly bondable 2D element having a first adhesive and a second adhesive, which is suitable for bonding objects with a metal surface to objects with a plastic surface, and which enables a stable and mechanically robust bond even at low temperatures. This is achieved through the use of particular combinations of different adhesives, tailored to one another and based on synthetic nitrile rubbers and reactive resins.

摘要:
The invention relates to a method for producing stampings from thermally activatable adhesive films, said method being characterised in that a) a thermally activatable adhesive material is first applied to a first carrier material, and b) the thermally activatable layer of adhesive material is laminated onto a temporary carrier material (“release liner”) under the action of heat, during a subsequent step. The release liner comprises at least one surface based on polyolefins, said surface being non-tacky at room temperature and activatable under the action of heat in such a way that it has adhesive properties. The method is also characterised in that c) the thermally activatable layer of adhesive material on the release liner is subjected to a stamping process.
