Provided is an aqueous primer composition including a first thermosetting resin that is a particulate solid at ambient conditions and a second thermosetting resin that is liquid at ambient conditions and acting as a reactive coalescent agent in which the first thermosetting resin is at least partially soluble. The second thermosetting resin acts as a coalescent agent to enable a continuous primer film to be formed as the primer is being dried before it is cured. The composition further includes a curative that is substantially water-insoluble and reactive with the first and second thermosetting resins. The overall composition can contain up to 4 percent by weight of volatile solvents, other than water and provides a shelf-stable primer that can form a continuous film without the need for added organic solvents.
