It’s possible to mix epoxy resin
Epoxy
Epoxy is a term used to denote both the basic components and the cured end products of epoxy resins, as well as a colloquial name for the epoxide functional group. Epoxy resins, also known as polyepoxides, are a class of reactive prepolymers and polymers which contain epoxide groups.
Is it possible to mix epoxy with polyester?
Impossible. Some epoxies will be inhibited from curing by the addition of polyester. A particular example of this is Resin Research epoxy - a friend of mine who is into surfboard manufacture accidentally mixed clear polyester (Silmar 49, catalyzed) with Resin Research epoxy (already mixed).

Why does epoxy resin heat up?
Chemical reactions generate heat when mixing epoxy resin. This is due to a so-called exothermic reaction. The extent of this reaction depends on the resin, the quantity mixed, and not least on the height of the mixing container. Therefore, here are a few things to consider.

The thorough mixing of the resin and hardener is essential to obtain an attractive, useful result later on. If you do not work carefully enough, there is a risk that incompletely cured, sticky spots may appear in the resin or that the hardness levels within a workpiece may vary.
How long can epoxy resin be stored?
To ensure that epoxy resin can be processed optimally, it should first be stored for approx. 12 hours at an ambient temperature of 20 to a maximum of 25° C. If this long storage period is not possible, the material can also be brought to the correct temperature by means of a water bath.
