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.
