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.
