4. Processing conditions
a.) Temperature – The optimal processing
temperature is 20–25 °C. Raising the tempe-
rature by 10 °C halves the pot life and dou-
bles the reactivity
Important:
Larger quantities (> 100 g) should not be
mixed at higher processing temperatures,
above all with highly reactive systems (short
pot life less than forty minutes). The mixing
vessel exhibits very low heat dissipation, so
its contents are very quickly heated by the
reaction. This can give rise to temperatures
in excess of 200 °C at which the resin com-
pound burns up emitting a great quantity of
smoke. This also affects large-volume casts
of highly reactive systems.
b.) Air humidity – The relative air humidity
during processing should not exceed 70%.
Also moist fillers can adversely affect curing.
Important:
EP resins accelerate under the action of
humidity!
Storage
The resins and hardeners can be stored at
least 12 months in their carefully sealed
original containers. The resins and hardeners
may crystallize at temperatures below +15
°C (60 °F). The crystallization is visible as a
clouding or solidification of the contents of
the container. Before processing, the crys-
tallization must be removed by warming up.
Slow warming up to approx. 50 - 60 °C (120
- 140 °F) in a water bath or oven and stirring
or shaking will clarify the contents of the con-
tainer without any loss of quality. Use only
completely transparent products.
Before warming up, open containers slightly
to permit equalization of pressure. Caution
during warm-up! Do not warm up over an
open flame!
While stirring up use safety equipment (glo-
ves, eyeglasses, respirator).
