Right, epoxy is exotherm. But for small volumes, the released heat during the chemical reaction is hardly benificial for the reactionspeed. With some raw basiccomponents you can get up to 1 week curetime.
Heating up has an influence on reactionspeed. That's true. The microwaves here are rather used as an reaction-initiator (the 'mixture' quickly cools down after removing it from the oven, but the benificial effect remains).
