Hi Xinyu Li,

Yes! Su8 is a good for molding but just for a limited amount of time. You can
use hydrophobic coatings on the su8 before and everytime you put the PDMS. Also
you can improve the adhesion of your SU8 structures to the substrate where the
su8 was spun by using the SU8 realese layer from Microchem Corp. in Newton, MA,
USA.

good luck!
