Calling adhesive gurus...?

[Freddyfruitba...]

I recently had a low-speed off on my BMW boxer twin, and fortunately my cylinder head protector did exactly what it was supposed to. However in doing so, an aluminium plate came unstuck from the main plastic body:

I'm probably overthinking it, but bearing in mind the adverse conditions (mechanical strength/ high temperature etc) I emailed the German manufacturer and asked what type of adhesive they use, and was advised it was the following, a 'single component polyurethane':

Now I can obtain exactly this stuff in the UK for sure, but it's no doubt going to be highly expensive, and truth be told, I've probably already got an equivalent in my glue collection here anyway. Would anyone who knows about this stuff be able to advise the specifics of what I should be looking for?

I would use something like this https://www.firestoppingshop.com/product/safire-high-temperature-adhesive?gs=1&gad_source=1&gclid=Cj0KCQjwzby1BhCQARIsAJ_0t5Oo-0FEnwNzVeLmzaBt0SexTb2Q3vH-L3_IBb3oMMggDio1yIZWqe8aAlvjEALw_wcB

However if you dont need the temperature Sikaflex is brilliant stuff, Use it on my boats all the time. There are some really fancy ones but this is my basic go to choice.

Edited to add, Ste beat me to this one but Sikaflex s epic stuff, Up with Loctite as a brand in my view.

Remember there are foaming and non-foaming polyurethane adhesives. If there is a slight gap and you can clamp the pieces firmly together as it cures, the foaming sort is better because it'll get a bigger surface area and fill any gaps. Squeeze-out is easily trimmed with a sharp knife once it's cured. If you can't clamp it firmly, the foaming will push the pieces apart slightly.

As above, gorilla original is a foaming polyurethane. Gorilla crystal clear is non-foaming.

I use West Systems G-flex epoxy for most adhesive jobs and it's what I'd use there. You need to briefly run a blue gas flame over the ABS just before you apply the adhesive then tape it down hard while it cures.

Or thin 3M VHB sticky pads?

Thank's a lot, all - much helpful info here.

I generally consider any polyurethane adhesive to foam to some degree unless it specifically says it doesn't (eg, gorilla clear).

Foaming is a good thing, it makes the join stronger and more flexible. It does however need to be clamped/taped down while it cures.

I haven't found any glue better than Serious Glue for gluing random shit together. It's not that easy to find, slightly expensive, and when you do open a tube it will probably go hard before you need to use it again but it's the best glue I have ever used.
