is it on a shore scale?
is epoxy shore d 85 is good?
and what will happen if i but a cayanoacrylate glue as a resin?
another question: how much the humidity of the room is making a difference?
what is a good scale for that?
85 is pretty hard, standard hardness for an epoxy. I know you can get 95 Shore D Epoxy.
You can’t really use cyanoacrylate as a resin. It cures with humidity, so the parts that are exposed will cure, while the parts that arent wont. It might take weeks for a single layer to cure.
Humidity affects certain resins more than others. Most materials can be handled in ambient humidity just fine.
