# I work with epoxy resin, what sanding additive is recommended?

Playing the same role as paraffinized styrene added to polyester resin, our EP217 additive allows more efficient surface sanding, with less clogging of your abrasives, on a more flexible working base. Add approximately 4% EP217 solution to your epoxy resin during the “hot-coat” step

**Please note, styrenes are dedicated to polyester resin; under no circumstances should they be used with epoxy resin.**
