Hi All,

I would like to use a micro moulding technique to cast a pattern into spun on
polyurethane.  I wanted to used a rigid material to pattern the negative easier
to align. I was thinking of SU-8 using photolithography but I am not sure if the
polyurethane would just simply peel of this.  Another other suggestions of
photoresists that would not adhere to polyurethane (PMC-790 by Smooth on)
