I remember reading about uv blockers that could be added to epoxy - any

I added graphite powder to an epoxy casting once. Because it is totally
opaque, it is a good UV blocker. This is probably not what you are
looking for, though. You probably want a UV blocker for a clear epoxy
coating.

adding chemicals to the epoxies messes them all up - so no in epoxy UV
blocker except pigments are available.

Note that most clear coat products have almost no uv blockers. Exceptions are
auto clear coat and a similar product offered by one of the epoxy vendors.
Also know of a 1 part waterbased acrylic clear with UV blockers but would
only use it on interior applications.

note that varnish makes a good epoxy UV blocking topcoat too.
