dielectric effect - Silicone Sealant

Example here

I think he's looking for potting material, something like Sylgard

ALL materials have a dielectric effect, including air. Now if you want less dielectric effect, consider vacuum...

Silicone RTV sealants usually cure by release of acetic acid; the effect on copper is ... unfortunate for electronics. There are silicone formulations that are compatible with most electronic components and wiring, if you can afford 'em.

Just try to buy the old style today. I has been gone for more than 20 years over the problem you remarked upon.

Not at the hardware store.

Now, what you're doing putting bathtub caulk on a circuit, I don't know...

If all you're looking for is conformal coating, you can get that in a spray can - I've used it before, but it was about $25 bucks a can... You might google[1] "conformal coating spray".

Good Luck! Rich [1] Should Google be capitalized as a proper name, even when it's used as a verb? thanks.

Regardless, before putting anything on, a sure insulator like many clear sprays of enamel can be put on critical parts before silicone or anything else. In one Nut's & Volts issue I read in boating, it recommended using the coating before siliconing wiring. Liquid TFE would be nice.

Lacquer does not insulate moisture like enamel does.
