Hello,


We have been using the acrylic  coating and it is failing.  My application
is a small, expensive  copper/solder circuit board which must operate
exposed in a greenhouse environment with humidity up to at least 80 per cent
and temperature from about 55 to 85 deg F.  There is evidence of green
corrosion products and peeling conformal coating which presumably need a
more appropriate coating.

We have to do rework and use agin same pcb boards. We would be very grateful If
anyone can be advised how to remove corrosion from the board.



thanks
