Hi all,
I got a call from our production. They stopped the board coating. All
boards get white and superthin veils, patterned like fractals or roses.
I'm at home because of illness, so I can't participate in their work
with the problem.
I asked them for how long they bake the board before spraying, and they
told me that  no baking is made at all. Does sound wrong to me. My first
theory is humidity in some form. Humiseal, don't have the article number
just now.
Anyone who has a tip?
I'll get pics sooner, maybe I can resize them for Steve's gallery.
Thanks in advance
