Seeking heatproof sealant/adhesive

I need a heatproof sealant and/or adhesive to fix a steel hob into a ceramic work top. Recommendations, please.

Is silicon not heatproof? It's what I used to fix a steel hob onto a laminate work top.

It may be. I know nothing! May I ask how long ago you did the job and--supposing it to be in your own kitchen--is it still in good condition?

The OP needs High Modulus Silicone

Available from central heating merchants and paces like Halfords who sell it as a gasketing compound such as Hylomar

Not the stuff you use to seal your bath with

Silicon is - but what comes out of a sealant gun is silicone

Are you sure (blue) Hylomar is silicone? The solvent for removing it is cellulose thinners. And it doesn't feel like silicone.

There are high temperature silicons, though - can be used on car exhaust systems.

I shall go to Halfords and ask them. Are their staff generally competent?

You're having a laugh?

They do sell various silicone jointing compounds, though, and the temperature range should be on the packaging.

However, the base of a hob won't actually get that hot. Or rather mine doesn't. Never so hot it would burn a finger round the edge.

Do a search on Ebay for 'High Temperature Silicone' Lots of products. You can then see if your local store sells them if you don't want to use Ebay. It's not something I've looked for in the sheds, but I'd expect Screwfix etc sell it.

Agree, this is not a high temp application, any high mod silicone will do eg:

silicone is fine to 80degC, many to 120degC.

For o/p, remember it should be a bed of silicone, not a post applied bead.

There are many high temperature silcone sealants around. Is 300C enough?

other things catching fire than the silicone deteriorating.

As to the OP, any silicone will do what he wants, as the surface temperature at the edge of a hob should never get above around 70 degrees C.

I always use No-Nonsense Sanitary Silicone from Screwfix, goes on well, and have never been called back to a bath or ktichen with it going black/peeling.

I always used silicone sealant for sealing exhaust gasket to exhaust, I never once checked what type just used whatever I had at the time. Dont know the temp range of an exhaust but would be very hot. Never had a problem.

Thank you for all replies.

I had used bath sealant and now it is wrinkled and breaking up. I don't mind replacing it since the hob isn't horizontal and it will afford an opportunity for me to level it. The hob edge does not get very hot, but it is hot enough to denature the wrong stuff. Thank you for pointing out that the hob goes on top of the silicone, I wouldn't have known otherwise.

The normal Hylomar (of RR fame) isn't silicone though. Istr Hylomar did bring out a high-temp exhaust silicone paste/tube, but the OP needs to be careful what he asks for - especially in Halfuds.

Interesting. Seems they make a range of products.

are generally self service for this sort of thing so it's up to you to select the correct one. There are a variety of gasket sealers or even gasket replacement goos that even Halfords stock.

Under heavy loads some exhaust systems get literally red hot.

700 Celsius for exhaust gas is quite normal.

800C every now and then if you've got a DPF (Diesel Particulate Filter) while it regenerates ...
