All of the commercial epoxy adhesives presented in App. B bond well to aluminum and to a wide variety of other materials. Sell22 has ranked a number of aluminum adhesives in order of decreasing durability as follows nitrile-phenolics, high-temperature epoxies, elevated-temperature curing epoxies, elevated-temperature curing rubber-modified epoxies, vinyl epoxies, two-part room temperature curing epoxy paste with amine cure, and two-part urethanes. 

Use the Bravo liquid handler to transfer 4.5 pi plasma to all wells of the assay plate, and spin down the plate and seal it with aluminum adhesive seal. After at least 17 h of incubation, read on PHERAstar plate reader at OD380 (r Note 9). 

With the Multidrop Combi dispenser and small metal tip cassette, dispense 3 pi Assay Buffer in columns 1-2 for Positive Control, and 3 pi diluted ENPPl in columns 3 8. With a different cassette, dispense 3 pi diluted ATP solution to all assay wells. Spin down the plate and seal with aluminum adhesive seal. Incubate for 110 min. 

Pretreatment is particularly important for structural adhesive joints such as those used in aircraft and motor vehicle construction. Aluminum adhesive surfaces are subjected to chromic acid treatment and an anodizing process, major factors in the overall joining costs. The disposal of used pickling baths is particularly demanding and expensive, especially in view of the CrVl ions resulting from the pickling process.

Brewis has recently discussed the nature of adhesives used for aluminum. The two major aluminum manufacturers. Aluminum Company of America (ALCOA) and Reynolds Metals, have published small useful volumes on all aspects of aluminum bonding, although these volumes are not recent.Another excellent detailed discussion of aluminum adhesives, particularly from the viewpoint of durability, is given by Minford of ALCOA,...

The adhesion of metal and ink to polymer, as well as the adhesion of paint and coating to metal, are of vital importance in several technologies. In the aircraft industry, aluminum-to-aluminum adhesion is being employed increasingly. The strength and durability of an adhesive bond depend absolutely on the way in which the adhesive compound interacts with the surfaces to which it is supposed to adhere, which in turn often involves pretreatment of the surfaces to render them more reactive. The nature and degree of the reactivity are functions of the chemical states of the adhering surfaces, states that can be monitored by XPS.

One characteristic of CAA oxides is that they contain significant amounts of fluorine. Sputter depth-profiles obtained by Auger electron spectroscopy(53,5s,65) show a buildup of fluorine in the barrier layer. Although adsorbed fluorine is considered detrimental to aluminum adhesive bonds (as discussed earlier in Section 2.4),( 2) CAA titanium oxides exhibit remarkable bond durability, probably because the fluorine is incorporated into the oxide rather than adsorbed onto it.
