Hi,
Exposing the SU-8 mold to Silane vapor for about 4 hrs helped big time. I
was able to peel the PDMS without destroying the mold master. I was
wondering if you could how many times can I use the mold once i expose it to
Silane vapor or should I follow the procedure everytime I cast PDMS.

Thanks a lot for your suggestions.
