8. Use
8.1. Recommendations regarding the paint to use
Generally speaking, all paints and varnishes used with the conventional pneumatic guns are
typically used with the Nanogun Airmix
®
gun as well. The dyes contained in the paint must be
less than 5 mm.
8.1.1. Viscosity
The best results are obtained with a viscosity that extends from 25 to 90 seconds, as measured
with the AFNOR Cup no. 4. Nonetheless, some paints with a lower or higher viscosity (e.g. 120
seconds or more) may be projected as well.
8.1.2. Resistivity
Use a paint whose resistivity is adapted to the Nanogun Airmix
®
gun version that you own. The
optimal resistivity range lies between 0.5 and 500 M
Ω
.cm. Weak resistivity yields a good elec-
trostatic covering, yet may cause returns on the operator in the event of insufficient booth ven-
tilation.
A much weaker resistivity level (e.g. 0.1 M
Ω
.cm) will short-circuit the high-voltage cascade and,
consequently, remove all electrostatic covering. A high resistivity (e.g. 1000 M
Ω
.cm), will greatly
reduce the electrostatic covering. The
SAMES KREMLIN
resistance meter "AP 1000" provides
for easy control of paint resistivity.
