Yes, your right. I think polyimide has problems with strong bases. Though
I remember having adhesion issues while tring to do a wet anisotropic etch,
maybe the etchant was EDP. It occurs to me that one of our researchers here
had another interesting release technique. Apply and cure PI WITHOUT
adhesion promoter. Then just boil it in hot water. I believe it comes
right off.

In our experiments Polyimide was attacked by KOH.
