Epoxy-Anode is a self-repairing primer containing 93% Zinc solids bound into an epoxy resin. If a scratch appears on the steel that goes through the topcoat and primer back to bare metal the zinc in the primer will react with the steel, this reaction will form zinc salts that will heal the scratch maintain the barrier and the steel will not rust.(Cathodic Protection)
