Adhesive for metal

[old_picker]

just wondering if there is a reliable metal adehsive available

[durwood]

3M make adhesives for metal so do some other companies, a lot of cars these day are glued together as are planes.

[NewLou]

Yup theres Heaps about heres a typical example:

Also have a look at certain epoxies that are dedicated to adhering ferrous and non ferrous metals..............

just wondering if there is a reliable metal adehsive available

What sort of metal is involved, what configuration and in what sort of circumstances is the metal being used? In light situations even plain old carbog is pretty good stuff.

In heavier duty situations, something like JB Weld with a metal filling is at the top end of the scale. It's very expensive but it can take lots of wear and vibe. I used some to fix a hole in a big chainsaw and 6 months later after some fairly heavy use its still there looking like new.

Depends on what you mean by reliable and how you are going to be applying loads to it.

Adhesive bonding of metal is good in many situations but it requires an understanding of how loads are going to be applied (shear or tension) and if the loads are static or cyclical in nature.

Easy answer is an epoxy adhesive.

[old_picker]

stainless and aluminium are the metals
load is not great but will be subject to a lot of sonic vibration

[Master Splinter]

You'll do best by abrading the surface of those two with 80 grit paper before gluing.

Try to avoid having the load applying itself in 'peel'.

Browse here (http://www.westsystem.com/) for more info on using epoxy.

Saw a pretty amazing adhesive at the WWW show this weekend. Basically they've been around for years and without having to try and remember the name of this particular distributor the glues are an anaerobic glue. Meaning they go off in the absence of air. They'll still go off eventually with air still present but take a long time. Do a search for Anaerobic adhesives.

You may want to check out the Loctite range. They have a huge range of very strong adhesives for all materials. Widely used in engineering and maintenence applications.
You may need more than one dependind on the application but my advice is ask a stockist who knows their stuff or call Loctite for advice.

As said, it depends on what you are gluing:
Paper template to metal -> Glue stick.
Plastic to metal (providing it isn't polyethylene/polypropylene) -> Epoxy.
Rubber (or plastics that epoxy doesn't like) to metal -> Contact cement.
Metal to metal -> Loctite.

loctite held all the seakings together at 817 squadron on the seakings in the navy...... maybe that explains something?:(

Sikaflex is generally regarded as the market leader in glues for metal. They have a range that covers most common needs. There is a lot of glue in the modern car holding it together, especially around the firewall. Glues avoid the ongoing problem of corrosion created by welding. Sikaflex is available in Bunnies which makes it readily available.

another vote for JB weld.

works great will alloy. :2tsup:


available from kmart in the auto section.

Sikaflex is my vote. I bonded a zincalume sheet roof onto a canopy on my old ute and the stuff never loses its bond or dries out even when exposed to constant and extreme heat.

Good for damping vibration as well.
Sika has a massive range of bonding compounds so you need to probably check their whole range or call tech support to get the best advice on which one to use.
