What glue for delrin?

A strong PSA is the only thing that'll stick it, and it's not permanent. Only heat welding - which ain't easy on Delrin - will permanently affix two pieces. Short of that, consider conventional fasteners.

Depends on required strength and load orientation (shear, peel, etc¡K) Spray Loctite 770 (primer), let it dry. Other products are called ¡§Surface energy activators¡¨. If you have access to a plasma etcher, that is the way to go!

Then use the adhesive of choice (cyanoacrylates and epoxys are best).

There's something called "Cyanopoxy" that claims to work. It includes a "primer" that presumably breaks up the chains near the surface so the glue has something to hang on to. A web search should turn up a source.

Sprinkle iron powder on one piece, put them together and tape them tightly and put them in the microwave for a bit.

k.o.

Is this a gag or would this really work? Why?

One method of welding plastic is to embed a piece of wire in the joint and then heat the wire from the outside with an induction coil (not that I've ever done this, but I've read about it). I don't know if a microwave would work or not.

It is pretty amazing Stuff.....

Can't be amazing enough to have to register just to look. Bob

This is a situation often addressed by makers of billiard cues, ie glueing delrin to wood. A special glue is required - one vendor is "Atlas Billiard Supply" at
