The present invention relates to primer compositions for adhesive bonding systems. The primer compositions may be in the form of sprayable aqueous dispersions, which are shelf stable at ambient temperatures for up to three months under ambient temperature conditions, and demonstrate a cure profile of 45 to 120 minutes within the temperature range of 220° F. to 350° F. within 60 minutes of application. Significantly, the inventive primer compositions are substantially free of chromate.
