High temp Adhesive/Protectant
High temp Adhesive/Protectant
(OP)
Hi,
Does anyone know a High temperature (350-400 F) adhesive and protectant I can use for a simple strain gauge on steal?
Most of the time I can just use some form of super glue for an adhesive, can not for high temperature.
As for a protectant I can normally can just use electrical tape or silicone rubber to cover the strain gauges after they are assembled. In this application I can not use tape because of temperature limitations and I can not use any form of silicone because the full assembly involves DC brushed motors that could be adversely effected.
Any suggestions would be greatly appreciated.

Of course I can. I can do anything. I can do absolutely anything. I'm an expert!

Masterbond, 3M, Loctite all didn't have a quick answer for me. waiting for response though. I will keep calling around as I was though.
RE: High temp Adhesive/Protectant
Your temperatures are a bit above what we deal with but we've found some of the Masterbond products work at fairly high temperature & when exposed to solvents.
Their website list several candidates for your temperature range and above

The only thing I'm not sure on is if the thickness/properties of these adhesives will work well for your application on strain gauges.

It's electrical tape though, but it is heat resistant to about 200 Celsius degree (392*F), so it might work.
Cheers.

It,s aluminium adhesive tape, which can resist temperatures over 250*C (482*F) used for insulating fireplaces flues.
RE: High temp Adhesive/Protectant
I am working with their applications engineer now, so hopefully something will work.

No, cant have silicone. The second one I also cant use because it is conductive. (I didn't mention anything about conductivity in the post, that was my bad)

Still waiting back on the protectant, again no quick answer for me.
