2.5 PROCESSIBLE WORKING MATERIALS
Lacquers which contain ingredients of explosion class IIA and IIB substances (maximum
ignition energy 0.24 mJ) can be processed with the GM 5000EA spray gun.
The spray gun basic version is suitable for processing sprayed substances with an
electrical resistance of > 150 kΩ (according to the WAGNER scale).
Equipped with a special product hose for low-resistance sprayed substances (available
as an accessory), you can also successfully process sprayed substances with an
electrical resistance > 50 kΩ (according to the WAGNER scale).
The application e ectiveness is always dependant on the composition of the product
being used, e.g. pigments or resin.
Conversion of Paint Resistance
There are paint resistance measuring devices available on the market that do not directly
measure the speci c paint resistance.
Multiplying the result of the measurement with the device-speci c cell constant (K), we
obtain the speci c resistance value of the product.
Example:
With WAGNER's paint resistance measuring device the cell constant is K =123.
Measured value according to the WAGNER
scale
Speci c resistance (RS)
Notice
Using sprayed substances with too low an electrical resistance, the application of
electrostatics does not show any e ect, i.e. there is no "paint wrap around" on the object
to be sprayed.
The suitability of the spray product with regard to the charging ability can be read from the
actual values for high-voltage (kV) and for the spray current (μA) shown in the illuminated
displays either on the VM 5000 control unit or on the spray gun.
High kV value, low μA value = ok.
Low kV value, high μA value = Excessive conductivity of the paint.
No wrap-around
Please contact your local WAGNER dealer and the lacquer manufacturer if you encounter
application problems.
