  • There are many reasons to use adhesives rather than fasteners. A very basic one is that fasteners weaken the surface where the drill is made, and all the forces are borne by the fastening point. With adhesives, forces are borne by the entire piece. How’s that for a neat trick?

    Another advantage is that you don’t see a rivet or screw head on your nice shiny surface.

    I never said signage was a 1:1 comparison with automotive, just that I’ve installed a lot of signs, some very large, whose structure was made of bonded aluminum, that many are over a decade old, that some withstand major stresses, and that none have failed.

    As to the longevity? Do you often hear about planes losing panels? Because there are a heck of a lot of bonded panels in airplanes, both commercial and military.

    Also, probably somewhere in your cars there are some bonded surfaces.

    Lastly, Lotus has been making their sport scar chassis mostly bonded aluminum for the past, what, 30 years, maybe more? There is not a single case of delamination in those years. Good enough for me.



  • Adhesives are used in many aerospace applications to bond panels and structural elements. Some Lotus racing and street cars chassis are bonded aluminum! Lotus are racing chassis specialists, making chassis for other racing teams.

    The space shuttle’s bottom tile heat shield, which withstood insane temperatures and stresses, were glued.

    Adhesive science is pretty cool. You may want to read up a bit.

    Take a look here. I’ve used their adhesives and 3M, also an impressive range, in a signmaking business I used to own. Not a single sign has failed in decades, weathering rain, snow, wind, very hot summers. We are talking pretty big surfaces, under pretty big loads and stresses.
