Resin Vs Varnish
The main difference you will notice right away between epoxy resin and varnish is the consistency: ArtResin epoxy resin is very glossy with a nice, thick surface when cured. When it comes to application, ArtResin is poured on and spread out. Its cure time is 24 hours until it's dry to the touch and 72 hours for a full cure.
Varnish is also shiny, though not quite as dramatic as the shine you get with epoxy resin, and it's paper thin. Varnish is typically painted or rolled on and has a much quicker dry time.
ArtResin epoxy resin is formulated with 2 different UV light stabilizers to protect against the damaging effects of UV light, whereas varnishes typically are not.
