Additives for Epoxy

The new Epoxy Resins are very complete – the new Resin Research Epoxies are UV stable, and cure without tack and with no need for added solvents. The hardener is a part of the epoxy system.  We do use and recommend one additive – Additive F, which is solvent based, as an aid to sanding cured epoxy. To keep Epoxy resins completely free of solvents, you do not need additives if you can wait for a full cure.
