Does anybody out there have experience using photopatternable PDMS (such as WL-5150 or WL-5351) and had any success bonding it to other PDMS? I've tried the plasma treating procedure that works with Sylgard 184, but it doesn't work with this stuff. I'm spinning on a layer about 30 microns, patterning it, and need to bond it to another layer of PDMS (or anything else that can serve as a thin membrane above the patterned layer and has a low modulus.) Thanks, Joseph Peach
