THE PROCESS
This is a method of applying electrostatically at-
omized coating material. The No. 2 Process
Handgun System applies a high voltage, DC
negative charge to the applicator bell, creating
an electrostatic field between the bell and the
target object. The target is electrically grounded
through its support (which may be stationary or
moving) or through an electrical connection to a
known earth ground.
A regulated pressure fluid system delivers
coating material to the bell when the gun is
triggered. There, the fluid travels across the
face of the rotating bell and is charged. The
fluid is atomized at the edge of the bell forming a
fine mist, which under the influence of the
electrostatic field is attracted to and deposited
on the target object. The forces between the
charged particles and the grounded target are
sufficient to turn most normal overspray around
and deposit it on the rear surface of the target.
Therefore, most of the spray is deposited and
overspray is controlled. This process makes
the No. 2 Process Handgun one of the most
efficient electrostatic spray products on the
market.
The No. 2 Process Handgun applies a DC
negative charge to the coating materials at the
point of atomization. The electrostatic charge
allows a more efficient, uniform application of
coating material to the front, edges, sides, and
back of products, making it highly suitable for
applying coatings to a variety of surface con-
figurations; large targets, tubular products, small
parts, fencing, etc. Because it is a grounded
fluid system, it is highly suitable for applying a
wide range of solvent reduced coatings such as
enamels, epoxies, etc.
One of the many features of the No. 2 Process
Handgun is that the electrical discharge, which
is available from the resistive charging brush, is
limited to the optimum combination of safety and
efficiency.
The No. 2 Process Handgun System includes
the Hand Gun, the High Voltage Power Supply,
the High Voltage Cable, and Fluid Hose.
