Heating Foam Resins with 245 fa
Blowing Agents
New foam blowing agents will froth at temperatures
above 90°F (33°C) when not under pressure, especially
if agitated.
Never
fill the 7 gal. (26 l) supply tanks beyond the 5 gal.
(19 l) line on the tanks, to leave room for some frothing.
At High Ambient Temperature (above
75°F/24°C)
•
Pour resins slowly to avoid frothing.

Only use Slow Recirc
, to avoid heating and
agitating the tank. If temperature doesn’t keep up,
set the function knob to Park
, then set to Slow
Recirc
again.

d. Set the Spray valves to Recirc.
e. Set the function knob to Slow Recirc

(24-32°C), then use Slow Recirc
to raise the
hose and gun to desired spray temperature.
•
If the top of the resin in tank starts frothing, do not
use Fast Recirc
any more.
