Abstract: A double-sided adhesive tape having a first outer impact-adhesive side and a second outer side that can be heat activated, comprising an at least two-layer product structure comprising the layers A and B. Layer A is an impact-adhesive layer chemically cross-linked by means of thermal initiation or an impact-adhesive carrier layer chemically cross-linked by means of thermal initiation. Layer B is a layer on the basis of a thermoplastic plastic. Layer A and layer B are in direct contact with each other, and the surface of layer B that is in direct contact with layer A has been corona- or plasma-pretreated. The double-sided adhesive tape is characterized in that the corona or plasma pretreatment is performed in an atmosphere comprising nitrogen, carbon dioxide, or a noble gas or a mixture of at least two of said gases.

Abstract: A thermally vulcanizable pressure-sensitive adhesive comprising a chemically precrosslinked, pressure-sensitively adhesive polybutadiene-polyurethane and ground sulfur, which during the heating phase remains pressure-sensitively adhesive, does not liquefy and hence in this phase, in which the vulcanization has not yet started and the curing has not yet commenced, has shear strength at least under load to moderate low, is able to transmit forces and hence to perform holding, a process for producing it, an adhesive tape comprising this pressure-sensitive adhesive, and a process for producing the adhesive tape.

Abstract: Method of adhesively bonding two surfaces by means of a reactive adhesive film system comprising at least two adhesive films (F1 and F2), each comprising at least one reactive component (R1 and R2), adhesive bonding being effected by a reaction which requires the presence of both reactive components (R1 and R2),
wherein, prior to adhesive bonding, a separating layer (T) which is impermeable to the reactive components is provided between the adhesive films which are to be brought into contact with one another for the reaction,
and the separating layer (T) is removed at least in part by means of a laser in order to effect bonding,
so that the adhesive films (F1 and F2) come into direct contact with one another and the reaction begins in the presence of both reactive components (R1 and R2), and reactive adhesive film system for use in this method.
