Electrical debonding of PU hot melt adhesives by use of conductive inks

The present invention relates to a method for reversibly bonding a first and a second substrate, wherein at least the first substrate is an electrically non-conductive substrate, the method comprising: coating the surface of the electrically non-conductive substrate(s) with a conductive ink; applying an electrically debondable hot melt adhesive composition to the conductive ink-coated surface of the first substrate and/or the second substrate; contacting the first and the second substrates such that the electrically debondable hot melt adhesive composition is interposed between the two substrates; allowing formation of an adhesive bond between the two substrates to provide bonded substrates; and optionally applying a voltage to the bonded substrates whereby adhesion at least one interface between the electrically debondable hot melt adhesive composition and a substrate surface is substantially weakened. Furthermore, the present invention relates to the bonded substrates thus obtained.
