Super Glue

[MaverickITA]

Dear friends,
I need an info on the glue tipically used to block the coil.

Super Glue is a standard Cyanoacrylate or no?
If yes, there is no risk to damage the enamelled copper?

Thanks in advance.

Best regards,

Yes.
Professional coils are wound with wires that are covered by solvent soluble glue, so that the solvent is applied on a wire as the coil is wound, and the glue cures as the coil is wound, binding the coil together. Nice and clean.
We amateurs use super glue.

Thank you.

However, I like to be an amateur...

Not all Super Glue is the same. I had some enameled wire I salvaged out of a TV
and the super glue melted the enamel and caused shorts!

I'm not sure how to tell which one might work...

Do you think that "one component colorless synthetic resin" can work without damage?




Type: "polyvinyl ester" for example.

Well it probably won't eat the enamel but it looks to be flexible.

You want a stiff substance to stop microphonics...

Seen two types of pre coated wire. One was oven baked the other you soften the glue with a solvent. Did find a source for the wire but never tried them. If I remember correctly cost was the deciding factor

Would like to here if anyone has tried these

Tried Super Glue on a 270 turn RX and the glue did not work too well. Every time there is a bump the detector sounds. Not sure why but suspect the glue does not penetrate to the center core of the bundle. Never tried coating as I wind. Suspect it would work.

Had success using epoxy resin coating the wire as its wound

I think you are right, it is a bit flexible.
