Most if not all of the off-the-shelf epoxies I've used have generated a fair amount of heat while they are hardening. This seems to indicate to me that these are exothermic reaction, i.e. they generate heat from the reaction.
The common practice at my last company was to apply heat (heatgun or hairdryer) to epoxied joints to get them to cure faster.
As I understand the chemistry though, adding heat to an exothermic reaction should slow the reaction and effectively take longer for the joint to cure.
Was my company's 'standard practice' wrong to be adding heat to epoxy joints and extending the curing time, or is epoxy some type of anomalous material that cures faster when adding heat to the exothermic reaction. OR, is epoxy actually an endothermic reaction and the heat perceived during curing is something else?
