Aofeng High Quality Polyurethane Foam Sealant
AOFENG high-quality polyurethane foam sealant is a single
component, moisture curing, multi-purpose polyurethane foam filled elastic
sealing material. The polyurethane foam sealant is a special polyurethane
product in which the polyurethane prepolymer, the foaming agent, and the
catalyst are packed in a pressure-resistant aerosol can. During the
construction, the aerosol colloid is sprayed to the part to be constructed
through the matching sizing gun or manual nozzle, and the forming, foaming,
bonding and sealing process is completed in the short term. The curing foam
elastomer has the advantages of bonding, waterproofing, anti-shrinkage under
the cold and anti-expanding under the heat, insulation, sound insulation and
even flame retardant (flame retardant type). It is widely used in the
construction of the door and window joints, the expansion joints and the
filling of the holes seal.
Basic
introduction
The general
surface dry time in 10 minutes (room temperature 20 ℃
environment), the whole dry time with the ambient temperature and humidity are
different, under normal circumstances, the summer dry time is about 4-6 hours,
in winter it takes 24 hours or longer to be dry. Under normal conditions of use
(and in the case of a coating on its outside), the estimated service life is
not less than ten years, in the temperature range of -10 ℃ ~ 80 ℃ cured foam
maintains good flexibility and bonding force.
Typical
application
Door and
window installation: the sealing seal between doors and windows and the wall,
fixed bond.
Advertising
model: model, sand table production, display plate repair.
Sound
insulation muffler: broadcast room, studio and to fill the gaps during decoration,
it can play a noise muffler effect.
Gardening:
flowers, gardening, light and beautiful.
Daily
maintenance: holes, cracks, wall tiles, floor tiles, flooring repair.
Waterproof
plugging: water pipes, sewers and other loopholes in the repair, plugging.
Packaging transport:
can easily wrap the expensive fragile goods, save time and fast, seismic
pressure.
Instructions
1. Before
construction, should remove the construction surface from the oil and dust, and
spray a small amount of water in the construction surface.
2. To be
applied In the 0 ℃ ~ 40 ℃
temperature range, and if to apply in the cold season, in order to ensure the
good results, it is recommended that the tank to be preheated in the 30 ℃
environment.
3. Before
use, shake the polyurethane foam caulking tank for at least 60 seconds to
ensure that the contents of the tank are even.
4. If to
spray the gun-type one-component polyurethane foam sealant, the tank should be
inverted and connect the spray gun with the tank by thread screwing, open and
turn the flow valve, adjust the flow then spray.
5. If to
spray tubular-type one-component polyurethane foam sealant, fasten the plastic
nozzle screw on the valve thread, put the plastic pipe at the gap, press the
nozzle to spray.
6. After
each tank spraying is completed, please use a special cleaning agent to clean
the screw part of the gun, each continuous construction is completed, please
use a special cleaning agent to clean the entire glue barrel, so as not to blocked.
7. Pay attention
to the spraying speed, usually the sprayed amount of injection to half of the
required volume. Filling the vertical gap should be from the bottom to upper. When
to fill the gap on the ceiling, due to the role of gravity, the uncured foam
may fall, it is recommended to use supporting way just after the filling, until
the foam cure and bond with the ceiling, then take off the support. 10 minutes
or so, the foam form hard surface, to cut the foam after 60 minutes if
necessary. Cut the excess foam with a knife and apply cement, paint or silicone
to the surface for decoration if needed.
8. Repair
and Cut After the foam is fully cured, it is noteworthy that cutting the foam
of the skin will reduce the foam strength and reduce the foam seal waterproof
effect
9. This
product is not resistant to UV, it is recommended to further coating on surface.
Safety
instructions
1. Do not
pierce or burn the tank and the empty cans, keep them away from the fire source
and heat source.
2.
Transportation, preservation process is strictly prohibited open fire, to avoid
the impact and sunlight exposure, tank temperature should not exceed 45 ℃.
3. Should
not be inverted, under the normal state the tank is with pressure itself,
improper disposal will be an explosion (or burst) danger.
4. Wear
protective goggles and gloves during construction and ensure good ventilation
are needed.
5. If the
foam accidentally touches the eyes and skin, wash it immediately with a
cleaning agent, then rinse with water and consult doctor if necessary. After
curing, the foam can only be mechanically removed.
6. This
product contains isocyanate components, uncured colloids are irritating.
7. Keep
the cans and empty cans out of the reach of children in order to avoid
accidents and hazards.
8. This
product is flammable, explosive dangerous goods, transportation and storage
according to the relevant provisions of the product, please store in the cool
dry place below 25 ℃, shelf
life is generally about 9-12 months.
