Which bonding agent

Hi Folks

I need to bond or stick 2mm aluminium platework together. What should I be using ?

In the past Ive used JB weld but Ive found it messy, difficult to use, too thick and takes a long time to set. Its not appropriate for the job I need it for.

Looking for something with low viscosity and sets reasonably quickly.

I feel 'super glue' is a cop out ( and brittle ) If there a loctite product suitable ?

 

Thank you

I have always used epoxy both for Aluminium and mild steel. Yes, it can be a bit messy, use disposable gloves. Loctite do have epoxy, see here.

Cure speed of 1 minutes sounds good

Pity, because super-glue would be my answer. Like all glues it's not strong against peeling or shocks, nor is it gap filling. I've not noticed it's particularly brittle between close fitting smooth surfaces. Could be wrong!

You can get high viscosity superglue that is a bit better (but not perfect) at gap filling.

It depends on the application, but some of these modern-day mastics/adhesives are super strong.

Loctite 330 is my go to glue for jobs like this..its in a tube like toothpaste quite thick and hard to squeeze out…put on one side of the job spray the activator onto the other side bring together and clamp if you need to.

3M has a good IRSA product, and will stand behind it. Just FYI.

Thank you folks

Loctite "Black Max" cyno (superglue) contains rubber particles and will be more flexible than the regular stuff. Being low viscosity it will spread easily in a flat joint. Without going to look in the workshop I think the number is 489.

Or slightly warmed Araldite spreads easy enough though as with most 2 part things a faster cure usually mean less strength

I would think an epoxy would be the best, maybe researching what the aircraft and car makers use ! Jaguar Landrover use it on aluminium bodied vehicles and much of what was riveted on aircraft is now bonded I believe.

Just my thoughts, John
