1.4 Field of Application (Intended Usage)
The VoluDrop Dispenser is suitable only for the exact drop application of
LOCTITE UV acrylics up to a viscosity of 15,000 mPas.
It is not suitable to dispense UV acrylics with anaerobic component,
cyanoacrylates, abrasive adhesives and anaerobics.
Only drop dispensing is possible.
Up to a viscosity of 5,000 mPas the dispenser is able to spit adhesives.
Spitting is possible form 3 µl up to 15 µl, non-spitting from 0.8 µl up to 3 µl.
Within a distance of 50 mm a feed motion of the workpiece is not necessary. The
dispenser should be mounted with the dispensing needle downwards.
-adhesive used!
The dispenser is used as a stationary applicator unit. It is mounted directly at the
dispensing position. The free end of the product feedline is connected to the product
reservoir.
For product reservoirs, 0.5 l and 2 l versions are available.
The control of the dispenser is provided by a control unit of the LOCTITE equipment line.

2 Description
2.1 Theory of Operation
The LOCTITE adhesive is transported through a product feedline to the dispenser by the
dispensing pressure in the product reservoir. This feedline has a PTFE-liner to prevent
curing of adhesives in this area.
When the ejector piston moves back the dispensing chamber will be filled. The adhesive
is spat under high pressure by very fast movement of the piston. During dispensing a
non-return valve prevents back-flow of adhesive to the reservoir.
The amount of product dispensed is controlled by the volume of the dispensing chamber.
Via a stroke adjustment the amount can be limited between 0.8 µl to 15 µl per shot.
As a matter of principle, spitting is possible with each LOCTITE dispensing needle. An
exact spitting is only possible with the conical needles.
Generally, the size of the needle should be adapted to the required amount.
