Mixing different types of epoxy...?

therod

Ok so I have a new Adams titanium Tight Lies 3 wood to assemble. But I discovered 2 problems. Problem #1: My regular epoxy. Part "A" of the epoxy-the bottle had been knocked over with the lid also knocked off, so all of it emptied out into the basket I keep all of that stuff in. A little mess, but not the end of the world. Problem #2: Part "B" of my quick set epoxy has hardened. Not sure why the quick set hardened, it'd been in the cabinet for maybe 2 years. Always covered. But hardened none the less. So the million dollar question...Can I mix part "A" of one type of epoxy with part "B" of another type of epoxy? They're both Maltby brands of epoxy, so I was wondering if I could mix the types of epoxy I was using, or if I would just have to order more. Anyone ever tried it?

A 2 cents answer to your million dollar question.

If the epoxy are shafting epoxy with the same curing time - quick set or 24 hours . I guess you could mix and use.
I would mix a small portion and let it sit in the room temperature, exam it after the curing time is due, to see if the epoxy set or not.
As for hardening of the resin, they all do that, depending on the condition you store it under, some will last a year and some will last more than a couple of years. If the RESIN had lost it's moisture and become hardened but still soft enough to be scoped up by a screw driver, it's ok to use. Be careful of the portion you use since the resin lost it's solvent it will be more concentrated. Again mix it up well to have the texture close to the newly bought.
I had used hardened resin and no issue there.

The only reasonable thing you can do is mix some up, let it cure and evaluate the result.

In general you can't just mix and match brands since they may not have compatible molecular weights so the quality of the cure is unknown. Even from the same source like Maltby this is a crap shoot. Maltby doesn't make the stuff they only re-bottle it so they may have changed suppliers since the last time you bought some.

If you've had epoxy for 2 years, you probably should replace it anyhow. Epoxy can get old and not hold as well anymore (according to what I've read) and it's fairly cheap insurance to just get some new epoxy. Wondering if the head of a club will go farther than the ball is not something I want to be doing as I take my back swing. I have, on the other hand, had the quicker set epoxy solid color part get thicker and tough to squeeze out of the bottle. I placed the bottle in warm water for a few minutes and it became much more like when it was new and could be squeezed out into a mixing cup easily. I haven't tried that with epoxy older than about a year though.

Just because they are both Maltby doesn't mean that they came from the same company and if it is compatible. Maltby probably gets it in large quantities and repackages it. Nobody here really knows for sure if it will work or what strength it might have. Just get some new epoxy. It will last for years if properly stored.
