I've used a negative resist stripped called microstrip. When heated to
around 50 C it removes silicone, epoxy and god knows what.

Subject: [mems-talk] pdms stuck

Hi all,

Some days ago, I used pdms with a silicon master (with SU-8
structures) to make a microfluidic device. Unfortunately i forgot to
silanize the silicon wafer and some small piece of PDMS stuck on it.
I don't have another master, how can remove completely the pdms?

I've already tried unsuccessfully to clean it with Acetone and
Isopropyl alcohol.

Can you help me?
Thank you
Emanuele
