Bond It 750ml Mega Foam PU Expanding Polyurethane Aerosol Gun Grade Gap Filler

Description:
A fast setting, multi‐purpose PU foam which bonds, fills, seals and insulates most construction materials. Can be
used as both gun grade or aerosol application.

Benefits:
w Universal applicator valve ‐ can be used at any angle.
w Can be used either as a gun grade version (Gunfoam
Applicator‐ Pat. EP2004520, EE05028, RCD1635764) or as an
aerosol version.
w High yield.
w Low curing pressure and moderate post expansion avoids
deformation of building elements.
w High thermal and acoustic insulation value.
w Specially coated valve ‐ problem free and will not corrode.
w Space saving as you only need to stock 1 can!
w Non‐shrinking.
w B3 Rating according to DIN 4102‐1.
Bond It MEGA FOAM is a one-component polyurethane assembly
foam, and is based on a moisture curing polyurethane prepolymer.
Foam does not shrink after curing keeping the risk of deformation
of joints and separation from the surface minimal.

Uses
The fresh foam adheres to all common building materials such as
wood, concrete, stone, plaster, metal, PVC and polystyrene.
however it will not stick to surfaces such as polyethylene, Teflon,
silicone, oil and grease and similar substrates.

Areas of Application:
u installation of window and door frames and entrance door
linings (where a clean and controlled backfill is required),
u filling of holes.
u insulation of penetrations.
u sealing of thermal and acoustic insulation boards.
u sealing and connection of joints.
u reducing the impact of thermal bridges.

Properties
The foam can be used at temperatures from +5°C to +30°C. The
cured foam is semi-rigid and predominantly close-celled. It is
resistant to temperatures ranging from -50°C to +90°C and to
ageing, but not to UV-rays. Noise and heat insulation values are
excellent.

Preparation
Surfaces to be bonded must be firm, clean, dry and free from
dust, grease or contaminants that may hinder adhesion. They
must be moistened well with water. All construction components
must be properly prepared prior to foam application. It is
advisable to have FOAM CLEANER at hand.
The ideal working temperature for both the can and environment
is +20°C. Chilled cans must be carefully warmed in luke-warm
water (below +45o
C) before usage but avoid heating above +50°C,
as there is a risk of bursting. Cans which are too hot, for example
after having been left in a vehicle during summer, must be cooled
using cold water. Protect adjacent surfaces with paper, plastic film
or other suitable material. The can should be shaken occasionally
during this process to obtain the required temperature faster.
Prior to work, and before the adaptor is attached, he can must be
shaken thoroughly at least 15-20 times.

Application
As from 24 August 2023 adequate training is required before
industrial or professional use.
The instructions for the can must strictly be observed. Use gloves
and eye protection and avoid skin contact.
With Straw Adapter: Hold the foam can in upright position. Screw
the applicator (straw) firmly to the foam can valve. For
application, turn the can upside down and press the applicator
trigger. Use the applicator trigger to adjust the foam output.
With Gun Adapter: Hold the foam can in upright position, turn
the gun to the can by holding the gun handle with one hand, and
turn the can with the other hand. Make sure that the gun is not
pointed at other persons when turning it. The can must not be
screwed to the gun with the valve upside down or by turning the
gun on the can. Care must be taken not to overtighten the
adaptor and not to activate the valve during this process. Turn the
can upside down and start applying. The foam output can be
adjusted by the gun trigger. Turn the can upside down and press
the applicator trigger, using the trigger to adjust the foam output.
The fresh foam will expand by 1½ to 2 times. Therefore care must
be taken not to overfill joints. Fresh foam spills must be removed

immediately within the tack-free time with Bond It FOAM
CLEANER. Cured foam must be removed mechanically.
Please Note: Moisture is needed for an even and rapid curing of
the foam. Inadequate moistening or overfilling of joints and
cavities may lead to an unwanted post-expansion of the foam.
Foam extrusion can be controlled accurately by varying the
pressure on the adaptor or gun trigger. For foam extrusion the
valve is pointed down but it will work through most angles. The
valve lever is to be activated carefully. Once a can has been
started, it should be used within four weeks.

Limitations
Cured foam is sensitive to UV light and
direct sunlight and therefore should be
covered with suitable opaque sealant,
filler, paint or other material.

Cleaning
Excess foam can be removed whilst still
wet using Bond It GUN FOAM CLEANER or
Bond It MULTI-WIPES. Cured foam can only
be removed mechanically.

Container Size
750ml aerosol canisters.

Shelf Life
12 months from date of manufacture when stored according to
manufacturers instructions in original unopened containers.

Storage Conditions
Store and transport upright, in cool, dry conditions between 5
and +30°C. (Considerably higher temperatures may reduce the
shelf life). Do not store at temperatuires over +50o
C. Keep away
from sources of heat and direct sunlight.

Disposal of Containers
Do not leave empty containers where residue could be harmful to
children, animals or the environment. Replace lids and remove
any containers to a central disposal point in accordance with local
regulations. Do not pierce can. In the event of spillage remove all
sources of ignition, ventilate the area, remove people from
confined areas. Material should be mopped up immediately with
an inert absorbent material such as sand, collected and placed in
a suitable container or allowed to vaporise.

Health & Safety
Extremely flammable aerosol. Please refer to separate material
safety data sheet for full handling, use and storage instructions.
Keep out of reach of children. It contains an environmentally safe
propellant, which complies to the latest EU regulations banning
all CFC-propellants. It is the users responsibility to determine
suitability for use. If in doubt contact our Technical Department
for advice.
Note: this information is for general guidance only, since site conditions
and labour are beyond our control. It is recommended that users make
their own tests to determine suitability.
