Actually what I am recommending is DuPont PC 1015 or 1020 photo Coverlay. It
processes similar to photo resist, you cure in an oven at about 320 F.  The
only problem is that you will need to change out your developer before and
after you process to avoid "goo" when the two different monomers meet.  The
PC 1000 is a photo sensitive acrylic and should still meet your customers
requirement, I think?

Thanks for your response. I always value your opinion. Unfortunately we
cannot use a flexible soldermask in this application - only the DuPont
material. Thanks. Steve Kelly
