Preserving Epoxy (Epoxicles ???)

"T o d d P a t t i s t" wrote

Pull the bag out,
squeeze out air, close it, knead the two components
together, use a pencil to push all the mixed epoxy to one
corner, snip off that corner and apply like a frosting bag -
the bigger the snipped corner the more you can apply
quickly. Tiny jobs use tiny snips.

Nice trick! I can guarantee that I will be using that method in the future!

Thanks!

This also works on epoxy primers, and, to a limited extent, 2-part
polyurethane paints. I would imagine that it also works on fuel tank
sealants.

Freezing slows down the chemical reaction and greatly extends pot life.

Its been a while since I took organic chem, but I seem to remember a
rule of thumb that said organic reactions slow down by half every 2
degrees C lower you take them.

50mm syringes from the farm supply store, or Woodworkers Supply works
great for small quantities if you can mix by volume. Woodworkers also
has small cups, sticks, and acid brushes for a reasonable price. No
need to resort to the freezer trick..............

Personally, I wouldn't feel comfortable with using previously frozen, mixed
epoxy for an airplane unless the epoxy manufacturer okayed it, but I'm a
coward. My advice is to get an accurate scale and only mix as much as you
need.
Remember, prepreg is purchased frozen & kept in a cooler until needed.
