Two-Component SPF Roof Patch Spray Foam
Handi-Foam Two-Component SPF Roof Patch Spray Foam is a
multiple purpose two-component polyurethane froth foam
designed within the international guidelines for protection of the ozone
layer, and with respect to the Montreal Protocol, 1987 and other
environmental guidelines, utilizing a non-flammable, non-ozone
depleting blowing agent to assist in the safety of the end user and
the environment. The pre-pressurized, portable two-component
froth systems are dispensed through the state-of-the-art HandiGun® froth dispensing unit, providing unsurpassed quality and flexibility in end-use performance.
Application Areas
Spray foam onto any clean, dry surface in any direction to insulate,
fill and seal various size voids, deaden sound or reduce vibration. It
is specifically designed to spray onto flat or irregular surfaces, and
to fill large cavities. Standard free-rise density for Handi-Foam SPF
Roof Patch II-75, II-145 and II-425 systems is 2.5 lbs/ft3 .
The patented and user-friendly II-75 and II-145 packaging system
provides many unique advantages, including:
Factory-attached dispensing hoses. No need to attach
hoses prior to use.
Handle is secured to tanks. No more handle popping out of
box. No more tanks falling out of the box when wet.
Easy to open box for immediate use.
Hoses extend from top of tanks. More reach. More stability.
The II-425 is packaged with the A component and B component in
separate boxes, due to the larger size.
Two-component froth foam systems will expand immediately upon
chemical reaction of A component and B component to a final
volume that is 3 to 5 times the dispensed volume, in typical applications, and may be as much as 8 times the dispensed volume in
specific applications, depending on various factors such as cavity
size, ambient conditions, etc. The foam will cure to a semi-rigid
closed cell foam upon the chemical reaction of component A
(polymeric isocyanate) with component B (a polyol blend containing
certain additives).
Handi-Foam SPF Roof Patch fully expands and dries tack-free
within 30 - 60 seconds, is cuttable in 2-5 minutes and fully cures
within 1 hour.
Handi-Foam adheres to almost all building materials with the
exception of surfaces such as polyethylene, Teflon®, silicone, oils
and greases, mold release agents and similar materials.
Optimum application temperature is 75°F (24°C) but may be
sprayed onto colder or warmer substrates, with slight effects on the
foam characteristics. Cured foam is resistant to heat and cold, -200
to +240°F (-129 to +115°C), and to aging, but not UV rays (i.e. sunlight) unless
painted, covered or coated. Cured PU
foam is chemically inert and non-reactive
in approved applications, and will not
harm electrical wire insulations, Romex®,
rubber, PVC, polyethylene (i.e. PEX),
CPVC or other plastic. It is approved for
use around wires, plumbing penetrations, etc., and contains no formaldehyde. Handi-Foam systems require no
outside mechanical or electrical power
source and are available in various
disposable kit sizes to meet specific job
application requirements. When
sprayed, the foam will create a seamless, continuous seal to insulate
and protect against dust, air infiltration
and pests.
Preparation For Use
Substrate must be clean, dry, firm, free of loose particles and free
of dust, grease and mold release agents. Protect surfaces not to be
foamed. Shake kits well before using.
Application / Use
After following instructions for set-up, kits are ready to use. Valves
must be in the upright position. Materials are dispensed through
hoses and mixed in the disposable nozzle.
With a nozzle attached to the Handi-Gun, dispense foam by
squeezing the trigger of the unit. To interrupt or stop foaming
process, release the trigger. Once foaming process has stopped,
the dispensing unit must be reactivated within 30 seconds or a new
nozzle must be installed (multiple nozzles included with each kit).
Fresh foam may be applied in several stages to reduce overfilling of
void or damage to non-rigid, confined cavities. Cured foam can only
be removed mechanically.
Important Note: Use only in well ventilated area or with certified
respiratory protection. Wear impervious gloves, protective eyewear
and suitable work clothes when using. Read all instructions and
safety information (MSDS) prior to use of any product. The product
contains no formaldehyde. Cured foam is non-toxic.
Product Storage
Store in cool dry area. Do not expose to open flame or
temperatures above 120°F (49°C). Excessive heat can cause
premature aging of components resulting in a shorter shelf life.
Handi-Foam is reusable by following product instructions.
