Have been looking for something to repair rheostats and heater & light switches where the resistance element has separated from the ceramic. Found these products that look promising.

Has anyone used them or can tell by the limited specs in the description which might work best. Possibly someone might have a recommendation for something else. I'm leaning toward the Rocksett for it's small size and cost but Autostic FC6 (their mid thickness brushable or spreadable adhesive) being thicker, might do better. The other is a casting type compound which might be similar to the stuff used on the elements which are encapsulated and suspended on the switches.

I emailed their solutions dept but not being a company with a huge order, don't really expect an answer anytime soon if at all.

It is not clear as to what u are trying to fix. Are u tring to fix the broken winding of the resistor or just trying to paste it back down to the ceramic????

Put elements back in the ceramic and also repair the type heater switches where the elements are encased in ceramic for short protection. Needs to be high temp, non conductive and strong. The original stuff is white and looks like a ceramic or plaster paste which was poured in, wire embedded into half full groove and stuff hardened around the wire. Other type looks as if it was cast around the element.

McMaster-Carr has some good high temp ceramic adhesives and putties:
