One way to improve adhesive bond durability is to preheat the steel prior to application, as used in the paint industry. Initial testing with phosphate and the chromate coatings has revealed that both systems improve the performance of the joint but in differing environments. The highly crystalline nature of the phosphate coating was found to give resistance in a humid climate. The limitation to improving the life of adhesive bonds in corrosive conditions is that the pre-treatment technology developed to date has been primarily for paint systems, where the paint adhesion is not structurally critical. In considering adhesive bonding, therefore the strength and durability of the bond provided by these pre-treatments may not be sufficient to guarantee the life of the component. This project was aimed at investigating the synergy between pre-treatment and adhesive technologies and develop mutually compatible systems. In evaluating and researching pre-treatment systems for adhesive bonding, careful consideration has been given towards the environmental issues that are currently in vogue.
