Howdy Evan:

As with all epoxies, the pot life varies dramatically with
temperature... But, during a nice 80 degree day, it's about 50- 60
minutes. I chose this combination due to the fairly low mixed
viscosity of about 450 cps, which gives a nice wet-out to all of the
glass / kevlar I've used to date. Note that the elongation % of
concern is that of the 'system', as opposed to just the hardner. See
for example:

http://69.239.32.181/Jeffco/Systems/...y=1314with3138

which is Jeffco's 1314 resin with the same 3138 hardner. The
elongation of the 'system' with a moderate post-cure is 5.5%, which
compares most favorably to Gougeon's Pro-Set 125/229 at 4.5%.

There used to be a similar 'system' page for the 1310-L6 / 3138
combination, but it looks like they've moved on.
