In cold weather, two-part epoxy in a double syringe-style dispenser can be difficult to squeeze out. If it’s a little sluggish, spare yourself the fight, and put the dispenser in a caulk gun. The dispenser fits right where the caulk tube normally goes and stays in place once you have the plunger against the push pins.

Better still, store the epoxy in a warmer location. Further, some epoxies have limitations as to what temperature they should be used at.
was using some boat builder's cold weather epoxy last winter on a renovation project. What they do not tell you...the epoxies that actually cure in freezing weather, are chock full of nasty volatile compounds! Luckily i had a carbon filter for my respirator handy, or i would have lost my liver on that job!
There are always small areas you can electric space heat to store epoxies. But the problem is, where they are applied and cure are not always heated.
