If this material is a
Cyanoacrylate (CA, or crazy
glue) or another material that activates with air or moisture, or reacts to metal,
then you will need a dispenser that will handle the properties peculiar to it.
To dispense a very thin material properly,
you now need to decide whether you want to use a syringe based dispenser or
whether you should use a dispense valve with a controller and a pressure
pot. Here are some things to consider:
Syringe dispensing of
Cyanoacrylates:
In some cases, an inexpensive
syringe based dispenser is used to dispense a CA or very thin material with exceptional
grabbing power. The syringe is loaded and kept upright and the material is
dispensed WITHOUT using a piston in the syringe barrel. The reason for this, of
course, is that the glue will grab your piston and glue it to the wall, or build
up a ridge on the interior of the syringe that will break the air tight seal
necessary for it to work properly.
The dispense tip in this case should be a
Teflon tip.
Valve dispensing of
Cyanoacrylates: Consider our two mainstays in the
dispensing of CA; the
Diaphragm Valve and the Pinch Tube Valve.
Both can be safely used with CA materials and safe
pressure chambers.
Other thin materials:
If the material is just thin, but not a CA,
the valves mentioned above will work and the pressure pots will be good too.
Also, the other IDS valves and syringe dispensers with a tight seal such as our
front closing
valve should work fine. Dispense through any of our IntelliSpense
dispense tips.
