GS,

Resin choice is really dependant on what you are protecting the PCB from. I would suggest that AR or UR would be the 2 that may be most suitable. Material manufacturers can give some good advice on material properties would be worthwhile giving them a ring and getting their recommendations. Good luck

Many thanks Saaitk,

The PCB to protect could be (fuel cut off control system against tiefs ...)located in between driver cabin and engine. I have done a quick look on HumiSeal Automotive Products, found Acrylic Resin, Model 1B66 should be a suitable resin. Any experience available on this forum about such resin or similar ?

Best Regards......GS

We use silicones - better high temp for underhood. For environmental reasons we haven't used acrylics or urethanes, but would like to try them. Silicones don't like underhood fluids and are permeable to moisture. We also have the problem of UAW workers who don't care for the smell of acrylics.
