Hi-Temp Epoxy

I don't think any organics can withstand that temperature. Think brazing!

Thanks for the answers, fellas... as luck would have it, a mate of mine in the aviation industry has the sheet metal workers on the job making me a stainless steel expansion chamber!! Fully tig welded.

Only down side is a weight gain for the beast...never mind, it does come for free, so I am definitely not complaining, here!

Thanks guys

A company called Sauereisen has made high temperature cements for spark plugs, spark igniters, etc., for many years. They are not epoxy resins, but they might have a product that would work in your application. They have a website where you could contact one of their application engineers.

another company that makes "inorganic" read ceramic adhesives is Toagosei. www.toagosei.net I've had some limited success with aluminum but any bonding at these temperatures gets difficult/

I am not sure if this temp is too high for J-B weld. I have used is successfully on an engine block.

I was thinking JB too. depending on exactly what you are doing jb gets pretty messy and would not spread very thin. Many epoxies have fillers sucha s titanium or aluminum or such.

JB is worth a look though.

JB Weld is good up to 600 F. I'm looking at it to test proof of concept at a lower speed, or for the first stage vehicle. This discussion has moved to

High Temperature Adhesive. FYI.

G'day, fellas, I was just thinking the same thing...I searched this topic, and found this forum (I am a newbie here)

I need to find a Hi Temp epoxy resin to fix a 2 stroke expansion chamber made from lithographic plate (alloy thin sheeting)

A good mate of mine made the "pipe" to suit a 44cc chainsaw engine I'm using in a 1/4 scale RC drag car...(can you post images here?)another thought.....look here

anyhow, silly me sanded it down to make it look nice. I fired it up on the weekend, and POP! I split the divergent cone at the seam. (Not happy, Jan!!!)

what would be the best way to epoxy the pipe back together???

I will use plasterer's mesh tape to give me a tension proof substrate, along with a medium to build coats. I looked at ITW polymers, and a titaninum based epoxy resin seems a good way to go - hi temp properties, along with thick viscosity.

I want a finished product that can handle exhaust temperatures, and I can play baseball with the thing!!!!

Any thoughts????
