PROCESSIBLE WORKING MATERIALS
Coating products which contain ingredients of explosion class IIA and IIB substances
(maximum ignition energy 0.24 mJ) can be processed with the GA 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).
When processing metallic lacquers, it is advisable to use the spiral hose.
The application eff 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 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)
Note:
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 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 on the EPG 5000 control unit.
High kV value, low μA value
Low kV value, high μA value
Please contact your local WAGNER dealer and the lacquer manufacturer if you encounter
application problems.
