    摘要： The present invention is directed to a method for detaching two substrates bonded by an adhesive, in particular by treating with a debonding agent. In addition, the present invention relates to the use of the method in recycling parts of the electronic devices. The method comprises the steps of: (1) treating two substrates bonded by an adhesive with a debonding agent comprising acetone and/or oleic acid at a temperature from 20° C. to 90° C., and (2) removing the substrates from the adhesive.
