Devcon specialise in making epoxy materials for repairs to machinery. For
example their Titanium Putty
http://www.devcon.com/techinfo/124.pdf is specified for repairs to machinery
where the repair requires a machined finish. This must be extremely hard
material when cured.

There are single component epoxies used in IC fabrication which have 94D
hardness ie. ME-430 http://emeigroup.com/pdf/EMHP%20Eng_3.pdf
