In US its sold in every hardware store for caulking windows, etc.
If you can get it, use GE RTV for electrical use. It will say on
back: "...releases methanol during curing" The GE II stuff says that
it doesn't release acetic acid during curing, but it sure smells like
it- probably acetic anhydride or some other acetyl compound. I say
this since aqueous solutions of acetic acid conduct electricity, and I
am never satisfied to fully let anything cure before using it.
Also, would only use clear silicone sealant, who knows what conductive
properties some of the pigments might have- like carbon black.
This stuff makes a bulletproof transformer. Try to keep air gaps out.
Nice thing about silicone is that it seems to be impervious to ozone
and UV radiation, which most other dielectrics, excepting teflon, will
crumble into dust after enough exposure.
