    • 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 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.
    • 通过使用导电油墨对PU热熔粘合剂进行电分离本发明涉及一种用于可逆地键合第一和第二基材的方法,其中至少第一基材是不导电基材 所述方法包括:用导电油墨涂覆所述不导电基底的表面; 将电可剥离的热熔粘合剂组合物施加到第一基材和/或第二基材的导电油墨涂覆表面上; 使第一和第二基底接触,使得电可脱粘热熔粘合剂组合物插入两个基底之间; 允许在两个基底之间形成粘合剂结合以提供粘合基底; 并且任选地向粘合的基材施加电压,由此基本上减弱了在电可剥离热熔粘合剂组合物和基材表面之间的至少一个界面处的粘合力。 此外,本发明涉及如此获得的粘合基材。
