Dear Colleagues,

I am currently working on a device that requires some processing that
occurs in acidic solution (pH4-5) at 90?C and I need to protect an area of
the product for times up to 1 hour. This will essentially require covering
the active area of the device, processing the device in the conditions
above and then completely removing the protecting layer. Does anyone have
any idea of what material might be suitable for this?

Thanks in advance,


Dr. Aaron Norman.
