Wire Varnish Aging
Wire Varnish Aging
(OP)
Hello All,
Is anyone familiar with wire varnish aging or degradation over time? I have had failures occuring and we have come to a couple of conclusions that there are two different wire varnishes being used....a polyamide-imide and an urathane acrylate. The other difference is porosity found in the potting material.
One of the suspected issues is the wire varnish degrading over time but we are unsure as to if this happens/how this happens/ or any information on that.
Any input is greatly appreciated.
Thanks!

I never did find information on the varnish degredation in my research, so I suspect that degredation over time doesn't occur enough for it to cause problems.
Thanks for the response!
