Hi all, I have recently wound a few small resonators, to make a few SSTC's. They are wound on normal PVC and also on glass. I am contemplating spraying them with Two Pack Clear the type you would use on a car or truck as a final coat. My motivation is really cost, accessibility and strength of the paint. Does anyone know if the thinners present in the paint will dissolve or degrade the insulating coating on the copper wire?
Maybe? if it's a two part paint, does it even have "thinner" in the conventional sense (like lacquer or oil-based enamel). Can you get a small amount to try as a sample?
Depends also on the wire. While everyone talks about it as Enamel Magnet wire, it's not really enamel, it's some plastic or another.
Does anyone know if the two pack paint it's self is a poor high voltage insulator?
It doesn't really matter all that much. The turn to turn voltage on the secondary is only a few hundred to maybe 1000V, and almost any film will stand off that kind of voltage.
Any ideas on how to test it? So far I have used an old 1000V mega tester in a pot of the liquid to measure the resistance between a couple of electrodes. It always reads above 200Mohm regardless of the distance between the electrodes. Thanks for any help.
