Yes and no!
The aircraft/ helicopter manufacturers specify different numbers but in reality it is the same resin for the bonding process with
fillers added, usually cotton flock "Flox" and fumed silica "Aerosil" mixed in to a shiny toothpast type consistency. The Lancair also
has mechanical fastening of the fuse shell joins to take any shear out of the equation. I recently used some Locktite/ Hysol on a
BK117 repair and paid about $800 for 900 grams! I don't think there resins are necessarily any better than other resins, as they
are really old technology, but they are certified by the manufacturer. The properties of epoxy resin are only optimised if they are post cured.
