I thought epoxies softened at about 70degs C?

As with all things, I guess it's what grade or brand you choose to use.

Products like "5 Minute" or fast-cure epoxies will have lower service temperatures. The most common brand in the U.S. is Devcon (part of the Permatex/Henkel family). It is rated up to 200oF so that would be around 90oC?

However, I don't use 5-minute epoxies. They do not have the peel or shear strength I typically want. Though this is rather a "redneck" product, I use an epoxy called "J-B Weld". It is a filled epoxy that takes 24 hours to cure. It has a maximum service temperature of 500oF (whatever that is in oC I don't know - 260c, Ethel ). They recommend baking a part at over 600oF if you want to disassemble or remove the cured J-B Weld. I'm sure the U.K. has similar high-performance products.

More info than you want....
