Help on Epoxy resins
(OP)
Pls help me to remove a coat of epoxy resin applied on a rubber.
A solvent to dissole the resin and leave the rubber(NBR) without harming will be appropriate.

RE: Help on Epoxy resins
Ethyl acetate is one possibility. At room temperature, NBR (BUNA) seems to be relatively resistant to this one, but most of the epoxies indicate "not recommended" at any temperature. It's also a component in the paint gun cleaner we use with epoxy here. The co-solvent used in that mix (xylene) wouldn't be such a good choice due to the potential to swell your NBR part.
What about sandblasting? NBR is incredibly wear resistant, whereas the epoxies aren't nearly so. Depends on the intended use and geometry of your part as to whether or not this is a good option.
