Also check out a product, Tetra-etch, by W.L. Gore Associates, made for
chemically etching Teflon in preparation for adhesive bonding.

Hi Chad: Delrin is an acetal polymer from DuPont. It does not wet very well
and usually requires a surface treatment or primer.
If you're going with Loctite I would recommend their Prism 401 used in
conjunction with the 770 primer. Also due to the surface structure of the
Delrin it has a slow cure speed even for cyanoacrylates. You may need to
increase your fixturing time.
If this doesn't work I would recommend a two part epoxy and mechanical
surface roughening of both surfaces; as others have also stated.
Good Luck

Anybody have some recommendations for glueing delrin and stainless steel
together. We're going through loctite and are getting nowhere. Any
help is much appreciated.
Thanks,
