PROCESSIBLE PRODUCTS
With the GM 5000EAC gun, paints can be applied which contain solvents of
explosion class II A.
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 transfer effi ciency is always dependant on the composition of the product
being used, e.g. pigmentation or resin.
Conversion of Paint Resistance
There are paint resistance measuring devices available on the market that do not directly
measure the specifi c paint resistance.
Multiplying the result of the measurement with the device-specifi c cell constant (K), we
obtain the specifi 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
Specifi c resistance (RS)
Notice
Using sprayed substances with too low an electrical resistance, the application of
electrostatics does not show any eff ect, i.e. there is no "paint wrap around" on the object
to be sprayed.
The suitability of the sprayed product with regard to the charging ability can be read
from the indicators showing the actual values for the high-voltage (kV) and for the spray
current (μA) the actual values are shown either on the VM 5000 control unit or on the
spray gun.
high kV value, low μA value
low kV value, high μA value
In the event of application problems, please contact your local WAGNER offi ce and the
paint manufacturer.
