"High" temperature adhesive

"High" temperature adhesive

Last summer I had some problems with vapor lock and I'd like to avoid that problem this year. I have some insulation material that I would like to install on the back side of the carb heat shield. It is a foil type material. I'm wondering if I could glue it to the heat shield with some sort of adhesive but I'm concerned that the temperature might make the adhesive not hold. I have some spray adhesive that I used to fasten the inside panel coverings but I'd be willing to buy whatever will do the job. If it will be too hot for any adhesive I would have to just use some small machine screws as fasteners.

You can try some two part high heat epoxy.

If you roughen the surface of the metal backing and degrease it... and if the insulation material is porous, you could try some of the adhesive/sealant used on wood stoves. I think a lot of those are based on "water glass" so the adhesive is a bit brittle once cured but it should work as long as the metal surface is roughened up to give it some "tooth" to lock into.

Exhaust temps get pretty hot, I think I would not go for any sort of adhesive, I would do what they do on MGB heatshields with their heat insulation pads, use steel rivets to attach it to the heat shield. You can get rivets in SS, that would be the prefect solution.

I glued some heat shielding fabric on my intake manifold that came with my supercharger from Moss. I have no idea what it was (unmarked bottle) but it was green and slimy and has held tight.

I helped the situation by adding a sensor to electric fan that allows it to run for about 4-5 min. after engines off.. cools down just enough.. Never have had a problem when running with E fan.. Electric fuel pump of course

I decided not to go with an adhesive. I used stainless machine screws (6-32) with large washers and lock nuts and I have no concerns about it coming loose. My fuel lines are also wrapped with insulation now. Now all I have to do is wait for warmer weather than an Ohio winter.

I've went that route before too, when restoring MGB heatshields, when we could not get new ones, it worked fine.
