Opened CA glue will definitely go bad.

I have found that with Tamiya liquid glues that if you do not screw The top tightly, during the warmer summer months some of the volitile components will evaporate.   This leaves the less volitile components.  These less volitile materials are not as efficient in melting plastic

yes, Tamiya liquid glue can go bad over time if not kept tightly capped

Other than tube glue, I can't recall it ever going bad.

I have a tube of Pactra non-toxic glue from about 1979/80 which is still quite liquid and most likely usable (as much as the early citrus-based non-toxic glue is considered usable).

How long does model glue last before it gets old? How many years does it last?

Does 5 min. Epoxy have a shelf life ? mine doesn't seem to be adhering as well as it used to.

 

I have had problems with epoxy in recent years even when it was not old, as far as sticking to styrene.  Someone said on this forum awhile back that the kit makers may be using different styrene than in the past.  Don't know about epoxy chemistry, but it does seem that way.  When I first had problems I blamed release agents, but I washed and cleaned kits thoroughly and it didn't make a difference.

I'm using tamiyas glue. the regular and extra thin cement.

 

I find the Tamiya bottled cement to last several years. I've yet to had one go bad. Hard to say exactly how many years though.

In my experience, when plastic glue goes bad, you'll know it. It will simply fail to hold parts together.

Hi;

     Well, the question is this. How fast do you use up a bottle? I usually have about a fine sludge in the bottom in about a year. The comment about super glues is correct. I use it a lot and I've noticed when I open the refill bottles( Very Large) I have about six months to a year of shelf life.  T.B.
