In what medium can I store a 2 component clear coat (unmixed)

I just bought some 2 component clear coat: MIPA 2K HS Klarlack CS 85

I bought it together with a hardener and some thinner both of which have caps that can be screwed on and off. However, the clear coat itself does not have a cap, it just has a flat surface with a boxcutter symbol (from which I take that I’ll have to cut it open and will not be able to seal it again).

Now I won’t be using all of my clear coat in one go so I’d like to store it in a container when not in use. The thing is I don’t know if the clear coat fluid has any properties that make certain storage mediums a poor choice. So I wanted to run it past some people before cans start exploding or leaking noxious fumes.

My current ideas are:

• An old paint can
• A glass mason jar
• An old cleaned UV curable resin container (black plastic so protects from sunlight)
