Description
of Epoxy Hardeners
All
working times(pot life) are based upon an
optimum working temperature of about 80 degrees
F. Temperatures variations will greatly affect
curing times, and when below 65F can sometimes
double curing times. Other factors that affect
epoxy curing can be moisture and humidity, as
well as the thickness of lamination.

Description
of Times Shown
- Pot
Life: Represents
the maximum amount of time that the mixture
can remain in your pot. Once applied to your
working surface(usually in thin layers) this
will greatly increase the time you have
before the epoxy sets.
- Set
Time:
This is the amount of time after the
epoxy is applied in a thin film that it will
arrive at a gel state, still wet, but no
longer a liquid. To recoat without sanding
between coats you must reapply after this
point but before the drying time has
completed.
- Drying
Time:
At this point the epoxy will be ready to
sand and has reached about 90% of its cured
hardness. Epoxy still might remain a bit
flexible at this point but will complete 100%
curing over the following 1-5 days. If air
temperature get below 60 degrees, dry times
can double from the times shown.

Our
fast epoxy hardener is great for cold weather
conditions or for those who prefer fast curing
times at normal temperatures. It is good for
