EkoPoxy primer is a waterborne, two-part catalyzed epoxy primer that is very easy to use, sands easily, has excellent corrosion protection and is very solvent resistant. We recommend using EkoPoxy on all firewall forward metal and composite components. It can be used anywhere except on fabric. It is ideal for the exterior of metal and composite aircraft where durability is a high priority, although EkoPrime can also be used in that application. This video explains the correct mixing procedure and application technique.
