02Y040A and 02GN070A are chemically cured, two-component, high solids, epoxy-polyamide primers that are suitable for application on aircraft and aerospace equipment. Component A contains the pigment and epoxy resin. Component B is a clear non-pigmented polyamide, which acts a hardener or curing agent for Component A. When these epoxy primers are used over properly prepared substrates, they provide a corrosion inhibiting, chemical and solvent resistant film suitable for topcoat. Films are resistant to immersion in water, jet fuels, lubricating oils and hydraulic fluids.
