Airhead plastic repair

I'm repairing a /6 instrument housing and need to know what glue to use. My first thought is ABS cement.

Any of you glued one of these things back together? What worked (or didn't)?

Is it a visible crack or the inner screw mounts?

If it isn't visible I find Plastex works well Plastex obviously I have no idea if it's available to you.

It's also known as Plastech and sold on UK Ebay Ebay link

Thanks Rob! Never heard of Plastex before - I'll check into it.

I experimented with some junk housing bits and ABS pipe cement; it seems to be working.

These housings usually have broken/cracked mounts where the brass inserts live. I think it's due to over-tightening in the factory plus possibly the screws seizing over time. Then when some poor bloke powers the screw out of there, SNAP!

I've use regular epoxy to fix those.

The repair this time was needed around the base of the lens - inside the rubber eyebrows. Not visible, but also couldn't be globby or the eyebrow wouldn't fit. It looks like the ABS cement is going to do the trick.

PVC (ABS) pipe cement contains a thickner that make it less liquid-y and might be hard to use on some repairs. The active ingredient in PVC cement is MEK, and it works nicely by flowing into the crack and welding the ABS.

Be careful with it-- MEK is nasty stuff.

Definitely! One whiff when the container is first opened is enough to tell if it's still good! So it's MEK that gives off that potent odor. Huh

Are you saying PVC and ABS are the same? I've tried to use PVC cement on ABS and got nowhere. As a matter of fact, Home Depot doesn't carry any cement specifically for ABS, instead something that's supposed to work for both. It didn't. However, ACE Hardware sells the good stuff!

I have used Locktite Super Glue Slow for that exact repair. It is thin (non globby) so it can be brushed like paint. The slow formula gives you some breathing time.

I've just had a look at the plastech ingredients. It's Methyl Methacrylate or MMA which you drip onto the fine powder. It's basically the stuff used to protect the spectators at ice hockey matches and the material used to make your helmets visor.

Another alternative

Chloroform

An organic solvent useful for bonding hard plastics and clear acetate

Ether

Can also be used on some stubborn plastics where retail products fail


I'm going back to sleep now.

you can weld ABS pretty easily,
There are kits where you get a high temp heat gun and abs sticks for welded.

You do it from the back side of the part.
