A one-part primer composition is provided. The one-part primer composition includes a first epoxy resin that is a liquid under ambient conditions a particulate corrosion inhibitor present in an amount of from 5 wt % to 30 wt % relative to the overall weight of the composition excluding carrier solvents and water, a curative comprising a primary aromatic amine, a silane coupling agent, a carrier solvent; and water homogeneously mixed with the carrier solvent and present in an amount sufficient to hydrolyze the silane coupling agent while preserving solubility of the first epoxy resin and curative in the carrier solvent/water mixture. The corrosion inhibitor is pre-dispersed in a liquid epoxy to break the agglomeration of the inhibitors, mitigate settling of the pigment and improve primer performance.
