Cyanopoxy (Cool Chem Integrator 75)

CoolChem De-bonder 400 (clean-up)
CoolChem Poly Treatment 311 (slippery plastic prep)
CoolChem Activator 310 (catalyst)

Delrin usually doenst like to be glued too much...

I think that it prefers thermowelding.

Many plastic glues are basically welding the plastic parts. There are solutions for smooth plastics, including some that work with delrin.

A family member used to own a manufacturing company that used delrin components. While they didn't need to glue/weld any parts due to the ability to do complex machining, they did experiment with different chemical bonding agents and delrin.

Interesting stuff but all I could find referencing it's use was for model making. Anybody got access to a destructive testing lab. I'd kick a few buck towards a starter kit to see if it's strong enough for use on real world sized parts i.e. gluing male p-port fittings or an ADV body to a delrin lid. That would certainly be cheaper than having to thread and o-ring large diameter holes, a real challenge for those without a mill or tapping machine.

Found this on McMaster-Carr:

Bondit B45TH

Epoxy for Difficult-to-Bond Plastics Use these two-part (resin and hardener) adhesives on polyethylene (UHMW, HDPE, and LDPE), nylon (all blends and glass filled), acetal (Delrin), PPS (polyphenylene sulfide, Ryton, Konduit), polypropylene, PBT (polybutylene terephthalate), PEEK, ABS, PVC, PET (Ertalyte, Petlon, Petra, Mylar, Dacron polyester), ETFE, PVCF, PVDF (Kynar), ECTFE (Halar), fiberglass (FRP), polyimide materials (Ultem, Torlon, Imidex, Pyropel, Vespel, and Kapton), neoprene, EPDM, butyl rubber, urethane, glass, metal, and concrete. Mix ratio is 2:1. Begins to harden in 45 minutes; reaches full strength in 24 hours. The 1.7-oz. cartridge will cover approx. 3 sq. ft; the 1.5-qt. can will cover approx. 75 sq. ft. Color is amber. Temp. range is -40° to +350° F. To dispense the 1.7-oz. cartridges, use the applicator gun (sold separately). To mix the adhesive as you dispense, attach a mixer nozzle (sold separately). Full package is 12.
Epoxy (also known as Bondit B45TH) requires minimal surface preparation. It's flexible and resists temperature extremes, chemicals, and impact. Encasing (potting) compound (also known as Bondit B45) is a thinner version of the epoxy. Use on all materials listed or use as a clear protective coating. It resists moisture and seawater and is an alternative to castable polyurethanes when encasing (potting) electrical cables, connectors, and transducer terminations.

Do you know if its safe to use in a breathing loop?

Hi all

thanks for help, as a matter of fact dupont did not designed this plastic to be glued... and it seems difficult to glue it.

I had thought of gluing delrin observing my tecme cell holder, I thought my tecme cell holder was made of delrin.

I'd like to machine a more personnal cell holder to fit my needs

not that the tecme ones are not good but only that I perfer my own builts just because I like to change everything all the time just for de fun of it.

but I doubt it is made of delrin now .

I think it must be a sort of pvc, martin wil confirm or deny this "info"

anyway the tecme cell holders are glued, I could smell the glue when the parts were new, it smetl like pvc glue

I think I will taper the parts I wanted to glue and then I will screw one part to the others.

regards

I would suggest talking to Master Bond. They make glues for practacally any plastic for industrial use.Master Bond Substrate Reference Table
