5.1 Applying Adhesive - Spray Adjustment
Turn the spray air adjustment control completely clockwise. Hold the applicator facing
away from you. Squeeze the trigger to extrude a bead of adhesive from the nozzle.
While continuing to squeeze the trigger, rotate the spray air adjustment control slowly
counter-clockwise; this changes the adhesive bead into an ever-finer spiral spray
pattern. Continue to adjust the control until a suitable spray pattern is obtained to suit
your application. To stop the adhesive flow simply release the trigger.
5.2 Adhesive Flow Rate Adjustment
The flow rate of adhesive is dependent on the air pressure to the piston, and this is
adjusted by varying the setting of the pressure regulator on the air supply to the
applicator.
The air pressure operating range for the applicator is:
Minimum
45 p.s.i. (3 bar)
Maximum 100 p.s.i. (7 bar)
6 Application Hints
As with all adhesives, performance depends on conditions of use. Suggestions or
recommendations contained herein are for guidance only, since actual conditions of
use are outside the supplier’s control.
•
Ensure that the surfaces to be bonded are dry, free from dust, grease, and
loose particles.
•
Apply adhesive to one surface only. Bring the two surfaces together as
quickly as possible; the faster the bond is made, the greater the strength.
•
A heavier spray pattern increases both working time and bond strength.
•
When gluing dissimilar materials, apply the adhesive to the least heat
conductive of the two.
•
On materials that are cold to the touch, a better bond can be made by pre-
warming them before applying adhesive.
•
Surplus adhesive can be trimmed using a sharp knife once it has cooled.
Should molten adhesive drip onto a smooth or polished surface, allow it to cool
completely before removal.
•
Spray adhesives can be applied directly to expanded polystyrene and other
plastic foams.
