Hi All,

I am planning on using SU-8 as a sacrificial mould for PDMS. After screen
printing the PDMS I would like to lift off the mould. I am thinking of using
KOH. The does have some effect on the PDMS but not a significant amount.

Anyone have any experiences to share on SU-8 (post exposed) lift off using KOH
before I try it myself?
