Hi everybody,

    I am pretty new to soft lithography using PDMS. Can anyone kindly tell
me the exact meaning of complete curing of PDMS? or rather how can I be sure
that my PDMS has completely cured? I have seen papers reporting that under
certain conditions there was uncured PDMS left behind particularly at the
edges of a master mould while peeling off the PDMS layer. Also I suppose
that for PDMS deposition of different heights the curing duration also is
different. Can anyone kindly suggest me some optimum range of temp , time
and PDMS thickness for complete curing of PDMS?

Looking forward for your help,
Thanks in advance.
