Hi,

It would seem to be a strange question, but anyone knows if glue sticks (hot melt) are electrically conducting ? May I use it to bond component to a material ?

Thanks...

It would be easy enough to test your particular glue with a meter. But I wonder if the behavior might be different at higher frequences.

Typical translucent white hot glue sticks (with nothing added, no sparkley metallic glitter, etc) are non-conductive, good insulators (so long as they don't melt away, of course).

As for whether you can use it to bond a component to a material, I've no idea, you didn't mention who/what/when/where/why.

I did a measurement and it seems to be a good insulator, but I dont know how it behaves under different freq. of course.

I want to bond components on ceramic (wall tile maybe), and using a glue gun was the first thing came up my mind. I dont know if it stands to temperature, is 60-70C a problem for them ? I have a pattex product as glue gun/glue stick, but I couldnt find it descriptive sheet or sth yet.

Thank you.

I would recommend trying a silicone sealant. For example, Dow 734 flowable sealant. It is rated for continuous use from -65-177 deg C. An additional benefit, is that it may provide some vibration control.

Judging from this post, I think hot glue is pretty safe:

As for the question about bonding to ceramic, I have no idea, I just remembered that thread when I read the original question.

This place sells various glue sticks for different uses.

They've got good prices and great customer service.

I don't understand why you aren't just telling us exactly what you are doing.

In general, the melting point of hot glue is higher than 60-70C but it may soften at slightly higher than that temp. Hot glue is never meant to be used on things that heat up!

It seems odd to be gluing something to ceramic if either is 60-70C though, that's quite warm and for some parts, might be a reason to consider heatsinking them, thermally conductive epoxy to aluminum.

I was just thinking to glue the components on the backside of ceramic (like deadbug) and mount the tubes on the top, purely for cosmetic reasons. However it seems it is not practical, both there are many components and I find that it is hard to work with ceramic.

Thank you for information on glue sticks though.
