Recommended Temperatures
The temperature indicator – not available on Froth-Pak
™
620
and 650 kits – on the side of the tank shows the temperature of
the contents of the tank, not ambient air temperature. For best
results, the tank contents should be at 75º F (24º C) or warmer.
Froth-Pak
™
Foam can be applied effectively in cool air tempera-
tures or on cool work surfaces (above freezing and less than
75% relative humidity) provided the kit contents are at least
75º F (24º C).
Cold weather notice
The proper liquid component temperature in spray foam
ensures a balanced chemical ratio, consistent tank pressure and
an optimal foam yield.
To achieve the optimal liquid component temperature before
spraying foam, store chemical indoors at a temperature
between 75-85º F (24-29º C) for at least one day prior to spraying.
Otherwise, the foam performance could be compromised and
ultimately could lead to a loss in yield. See Section 7.1, Tempera-
ture, and Section 11, Tank Heating.
DuPont also recommends that you rock each kit back and forth
before opening the valves for the first use to ensure optimum
foaming of Froth-Pak
™
Foam Kits.
If after storing the product indoors and rocking, the kit is not
performing properly, please stop spraying and access the
trouble-shooting tips in this brochure or contact the Customer
Information Group at 866-583-2583.
3.1 System Purging and Testing
1. DO NOT breathe vapor or spray. Proper PPE and
ventilation are required. See product SDS and Section 2
of this manual for further information. Follow all
precautions for product.
2. Dispense liquid materials in an appropriate container for
about 10 seconds. This is to verify proper chemical flow.
3. Clean any liquid material from the Insta-Flo
™
Gun
face using a rag.
* Time depends on ambient and chemical temperature. See chart on next page
for nozzle change out times.
