Thermobondingverfahren, adhesive film, process for producing an adhesive film and the use thereof

Process for the thermal bonding of two to Mating components, wherein the adhesive surfaces of the two components to be joined are brought into contact immediately prior to bonding with an adhesive film, and the adhesive film is then thermally cured, wherein the adhesive film in a separate process step by pre-curing of a liquid preparation is obtained on a surface, which is not part of the components to be joined, characterized in that the liquid preparation is obtained on the surface by mixing two mutually assembled separately components a and B immediately prior to application, wherein - Component A contains at least one compound having two or more blocked isocyanate groups and one or more further additives, - Component B at least one compound having at least two reactive groups selected from hydroxyl groups, thiol groups, primary amino groups and secondary amino groups, and is also free from epoxy groups, as well as more further additives or, - at least one of components A or B as an additive containing at least one epoxide prepolymer and - at least one of components A or B as an additive at least one amine group-containing curing agents for epoxy prepolymers having an epoxy resin is formulated separately from the at least contains.
