Zusammenfassung:	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. La présente invention concerne des compositions primaires pour systèmes de fixation par collage. Les compositions primaires peuvent prendre la forme de dispersions aqueuses pulvérisables, qui sont conservables à des températures ambiantes pendant une durée maximale de trois mois dans ces conditions, et présentent un profil de durcissement compris entre 45 et 120 minutes à une température allant de 220° F à 350° F dans un délai d'application de 60 minutes. Les compositions primaires de la présente invention se caractérisent en ce qu'elles sont sensiblement sans chromate.
