Hello everyone,

I was wondering if anyone knew of a good dielectric material that can
withstand an AC voltage of greater that 700 volts?  At the same time I am
looking at a coating thickness of 1.5 to 2 microns.  We have been trying
to actuate salt solution (highly conductive KCL) using SU-8 2 and Teflon
for microfluidic research purposes but so far most of my efforts have been
in vain.  I tried SU-8 10 which gave me an approximate thickness of 30
microns and I guess it was too  thick.  If anyone has had any success with
some coating for salt solution, I would appreciate it if you could share
that with me.  Thanks a bunch in advance,
