Operating Guide
be accessible to individuals without proper PPE, loosely cover,
and allow it to stand at least 24 hours. Dispose of the waste
container in accordance with federal, state, and local
regulations.
2.7.2 “B” Chemical, POLYOL
If the “B” chemical spills from the tank, hose, or
Insta-Flo
™
Gun, wear all PPE, dike and isolate the spill
area. Keep unnecessary and unprotected personnel from
entering the area. Soak up the residue from the surface
with soap and water. Discard in accordance with federal,
state, and local regulations.
2.8 Cautions
2.8.1 Storage Temperature
Recommended storage temperature:
60°–80°F (16°–27°C). Storage below 60°F (16°C) is not
recommended. Do not store at temperatures above
120°F (49°C).
2.8.2 Building Codes
In many areas, building codes may restrict the use of
cellular plastics or polyurethane foam in exposed,
interior finishing material applications. Under certain
application code, the use of these materials may be
prohibited. The foam produced by this product is organic
and may constitute a fire hazard if improperly applied.
Consult local building codes.
2.8.3 Surface Temperature Restrictions
Polyurethane foam should not be used in direct contact
with chimneys, heat vents, steam pipes, or other surface
areas that exceed 240°F (116°C). The foam should not be
left exposed or inadequately protected for both interior
and exterior finishing materials. It is strongly recom-
mended in all applications that the foam be protected
by approved facings and coatings.
2.8.4 Open Flame / Spark Source
Do not smoke or operate the system in close proximity
to an open flame or spark source. Ensure pilot lights
are off. Welding on or near cured polyurethane foam
requires special precautions. Consult DuPont for
instructions.
2.8.5 Excessive Foam Dispensing
Do not apply excessive thicknesses at one time as this
may result in spontaneous combustion. For thickness
greater than two inches of cured foam, dispense foam
in multiple layers, allowing the heat from foaming to
dissipate between sprayings.
2.8.6 Isocyanate Contamination
Isocyanate and water do not mix, and this can happen
even from the water in the air. The material will solidify
and then the gun and hose will be unusable. The best
thing to do is to take care of the guns and hoses by
using the entire kit within 30 days of opening.
WARNING: Water reacts aggressively with isocyanate
(“A” chemical/ISO). Reactions within a confined space
such as within a hose may present a safety concern.
Even small amounts of water vapor may cause a block-
age or an adverse reaction. Water carried within the
polyol (“B” chemical/POLY) hose to the point where
blending with isocyanate occurs must be avoided.
2.8.7 Confined Space
When preparing a site for spray foam, all considerations
for potential confined spaces must be taken and all
OSHA requirements must be met if applicable.
2.9 Training
DuPont does not recommend use of Froth-Pak
™
Spray Foam
Insulation and Sealant Kits without having completed the

health exams and fit testing, cartridge change out schedule,
required OSHA documentation), having completed review of
the instructions herein, and having reviewed the Safe Use and
Handling presentations available at: https://www.dupont.com/
