    Ultimate Paint Adhesion: Lumidize® Aqueous Pretreatment
    [​IMG]

    Low toxicity, fast-cycle electroplated pretreatment maximizes adhesion of paints/powders by chemically binding them to the substrate. Binds any conductive surface to epoxy/urethane topcoats. Exceptional anti-corrosion for vehicle manufacturing, aerospace; t...

    I just didn't know where else to put it. Interesting that it can replace the primer coating or is the primer coating.

    On their site somewhere it says that it makes epoxy adhere better. They were referring to epoxy paint, but if this stuff makes epoxy paint stick to aluminum then it might make epoxy glue stick to aluminum. If that proveso ut, then structural metal bonding on homebuilt airplanes may emerge from the shadows and cobwebs of the past...

    It is conceivable that in conjunction with graphene you could have a bond rivaling brazing in strength?

    What would the Graphene do to make the aluminum itself more bond-able? My understanding was always that the microscopic oxidation layer on the aluminum prevented a good bond from happening with any adhesive. If the Graphene made the glue stronger, but the aluminum itself still didn't like glue, what is the gain?

    Exactly.
    Graphene would bond to the Lumidize? Lumidize would be bonded to the aluminum. If that works the potential is for an extremely light and strong joint.

    Corrosion due to galvanic action is a concern?

    Well, if the Lumidize is a chemical (or electro-chemical) process that changes the aluminum, then it may also change the galvanic or oxidation properties of the aluminum.

    I believe that is the beauty of Alodine and other "conversion coatings".

    Maybe the nice folks at Carnegie-Mellon can provide some of that info, and then some of our scientific brain trust here on HBA can convert that into "Bonding for Dummies" so I can understand it.

    I can hear it now, the airport Barbershop Quartet singing "Sweet Alodine" :)

    Hmmm, no mention of fatigue life impact, something makes me think there will be an impact but how much?
