Does anyone know if epoxy can be used for - Arlin Eastman - 02-08-2024
drinking cups?
I have used casting epoxy for vases to waterproof them but nothing says NO about coating inside of a cup with it.

Ask the manufacture of the epoxy if it is approved for food contact. I know there are epoxies approved for water tanks but unless the particular epoxy was tested and approved you won't see a yes. Epoxies come in too many flavors to say all epoxy is ok. Roly

I did a lot of checking the internet and all of it says once cured it is good to go but total cure is up to a month.

The manufacturer for the specific epoxy that you are considering should have a Safety Data Sheet (SDS) (what we used to call a Material Safety Data Sheet (MSDS)).
The SDS is primarily concerned with safety issues for the person handling the raw materials and the as-mixed epoxy, but some mention the as-cured material.
Some of the modern epoxies are food safe when fully-cured (however long that takes).
The epoxies that I helped my father with doing fiberglassing for boats were some that I would never want to trust to drink out of. That was 60ish years ago and there were materials in the catalyst that were definitely not people-friendly.
It is sorta like needing to understand what wood is safe to make tea out of: sassafras - good, hemlock - bad.
