LATENTLY REACTIVE ADHESIVE FILM WITH A COMPONENT WHICH CAN REDUCE THE SURFACE TENSION OR THE INTERFACIAL TENSION

摘要

The invention relates to a latently reactive adhesive film which has a thermoplastic component that has a melting temperature T(melt) of 35 °C ≤ T(melt) ≤ 115 °C, preferably 40 °C ≤ T(melt) ≤ 100 °C, particularly preferably 40 °C ≤ T(melt) ≤ 75 °C, more preferably 40 °C ≤ T(melt) ≤ 60 °C, and which contains functional groups that can react to a latently reactive crosslinking agent, wherein the latently reactive crosslinking agent has a start temperature T(start) of 40 °C ≤ T(start) ≤ 120 °C, preferably 45 °C ≤ T(start) ≤ 110 °C, particularly preferably 50 °C ≤ T(start) ≤ 100 °C, more preferably 55 °C ≤ T(start) ≤ 90 °C, wherein T(start) ≥ T(melt), and contains at least one substance/material/component which can reduce the surface tension of a liquid and/or the interfacial tension between two phases and improves the adhesive properties of the latently reactive adhesive film, in particular the adhesive strength and/or the moisture/heat resistance.
