Air Sprayable Seam Sealer Applicator
Nozzle Purging
A characteristic of the Air Sprayable Sealant and the Sprayable Seam Sealer Applicator Gun is that some
sealent continues to flow out of the nozzle after the trigger is released. In order to control this flow of sealant,
a purging method to remove the excess sealant in the nozzle was developed. The correct purging method
is as follows:
1. Do not change the plunger or air atomization pressure setting that were used during the application of
the sealant.
2. Squeeze the Air Sprayable Seam Sealer Applicator Gun trigger to approximately of the full trigger
action, using. If have not ,it will be leak for throttle valve. This will clear the spray nozzle of sealant.
two fast, short strokes. Only air shout come out the nozzle. This will clear the outer nozzle of sealant.
Caution: During the purging cycle, the plunger pressure (GREAN VALVE) must be SET at ZERO and
the air atomization pressure (RED VALVE) must be Set LOWER than 4. If pressure is set higher than
4, the procedure will create back pressure and cause the plunger in the cartridge to reverse
discharge sealant into the gun barrel. It will also cause applicator gun failure and void the
manufacture’s warranty.
Pressure Valve Settings
Technicians will need to adjust pressure settings and vary nozzle tip distances from the surface in order
to achieve the desired appearance of a bead, sprayed seam and coating. The air line pressure to theAir
Sprayable Seam Sealer Applicator Gun shout be controlled via a pressure regulator and operated in the
range of 50-90 PSI . ( DO NOT EXCEED 90 PSI )
When the applicator gun pressure and the distance from the surface are adjusted appropriately, no
overspray is observed. If overspray is experienced, check the air pressure to the gun. The following
pressure valve setting are listed as general guidelines for producing the desired patterns.
BEADS SPRAYED SEAM COATING
Adjust red valve to: 100–150
Adjust blue valve to :
NarrowBead 15
0 - 300
WideBead 35
0- 550
Heavy Bead 600- 900
*Spray at a distance of 0 – 1 inches
from the surface to minimize overspray
Adjust red valve to 450-600
Adjust blue valve to 350-550
*Spray at a distance of 6 – 10 inches
from the surface to minimize overspray.
Adjust red valve to 200-350
Adjust blue valve to 600-900
*Spray at a distance of 6 – 10 inches
from the surface to minimize overspray.
