Super glue in HV capacitors?
      #11280 - Sat Aug 01 2009 09:36 PM

Does anybody know the dielectric strength, and constant of dried super glue?

Ok, It has a dielectric constant of 3.33.

Super glue adsorbs water, so I would not use in with high voltage circuits. There is a liquid polystyrene glue which works well with HV.

Would "gorilla glue", or model glue work well?

Model airplane glue might work since it is solvent based. I would not trust Gorilla glue with HV.

Ok, no superglue in final designs. A trial bottle capacitor sprung a leak when on it's side. I was able to get 2nf out of it. Also I mean for model cars. The kind that "melts" the pieces together.
