Can anyone tell me what a "normal" aviation grade expoxy resin
consists of? What about resources that will help me to understand this
so I can make an informed choice.

Dow epoxy resins and hardeners seem to be widely available throughout
SE Asia, and their properties are well known. You're looking for a
system with low to medium viscosity, high glass transition
temperature, room temperature cure. Dow talks a lot about their
resins, but not much about their cured properties. But here's some
suggestions: resins DER 331 or 332. Hardeners DEH 29 or 39. They
appear to have about the right properties.
