Hi everyone, I am trying to bond PDMS Kapton, however, I am also having problems in keeping the bond stable. Kapton comes off once treated with acetone. This query was posted On Memsnet sometime back. So, if someone has found a solution to this problem, please do let me know. Thanks in advance, Forum Harsh Sundani writes: Hi, I am trying to bond Kapton film to PDMS layer (spun on a Si wafer). The film bonds well to the PDMS layer. However, it starts coming off when treated with acetone and IPA ( in an ultrasonic tank) for around 15 min. Could anyone suggest a way to increase the adhesion between PDMS and the Kapton film, so that it can be treated with IPA and acetone without damaging the bonding? PS: The PDMS layer was cured at 100 C for 60 min. Thank you. Regards, Harsh.D.Sundani
