Preparation of paint
This system can be used for electrostatic coating with almost all types of synthetic resin paints except
some types of paints. It is not necessary to specially prepare a paint by mixing.
However, some paints require adjustment using a solvent to improve the electrostatic coating effect.
Also note that a sufficient electrostatic coating effect cannot be expected from some paints with an
extremely low electric resistance. Check the electric resistance of the paint with a paint ohmmeter.
A high electrostatic coating effect can be obtained with a paint resistance between 10 and 60M
Ω-cm.
To determine the acceptability of the electrostatic coating effect, ground a
20 to
30 steel pipe and coat it from the front surface. If it is coated to the rear end, the
electrostatic coating effect is considered to be sufficient.
Note that very little electrostatic coating effect can be expected from a metallic
paint or other conductive paints with an extremely low electric resistance.
There is a possibility of dyspnea or organic solvent poisoning.
Some substances contained in the paint or solvent do harm if inhaled or
contacted to your skin.
Follow the instructions in the Material Safety Data Sheets provided by the paint
and solvent manufacturers.
Work in a well ventilated place so as to prevent accumulation of hazardous
substances.

Operating procedures
For the paint pump and controller, thoroughly read the operation and maintenance manuals for them.
(1) Before starting operation, check that the paint and air hoses and connecting cable have been correctly
installed and that the paint pump and controller completely grounded.
There is a possibility of fire or explosion.
Completely ground the gun and the product to be coated. The electrostatic
coating process uses the high-voltage electrostatic phenomenon and positively
generates static electricity. If not properly grounded, they may discharge
static electricity or generate sparks to cause fire or explosion.
(2) Immerse the suction pipe of the paint pump into a mixed paint so as to suck it in and set the pressure to
a low level between 2MPa and 3MPa.
(3) Check that the power switch on the controller has been set to off. First, spray a small amount of paint
into an empty can or the like with no nozzle mounted on the gun and the gun trigger unlocked. Thus
the foreign matter and air from the paint circuit are discharged.
