conductivity of hot glue?

[Dominick22]

Is hot glue conductive? I mean is it at all??? I wouldnt think so, but I mounted an led using is and it os smeared across both the neg and pos terminal. It was fine at first and then began blinking after a few hours of use. Now, it is totally dead.

Is there a small conductivity in the glue that slowly killed it?

Thanks,

No it is not, well maybe in the 50 mega ohm range, not enough to ever effect an LED.
Check your voltage and current sounds like to much voltage.

Why not try a test? Put a blob on something you know to be non-conductive, let it cool and measure with your probes at specific distances

Good idea--Ill do it although my meter is not very sensitive!

Run of the mill hot glue is LDPE, Low Density PolyEthylene. That is an excellent insulating plastic. Really excellent as in good for many kV DC per mm.

Your problem might be just from running too much current through the LED, or perhaps the heat it received while the hot glue was applied and setting got to it. I doubt that though.
