AIRCOAT ATOMIZING FLAT JET SPRAY PROCESS

In the Brillant AirCoat process, high pressure of 3-15 MPa; 30-150 bar; 435-2176 psi is used
to atomize the material. The AirCoat air at 0.05-0.25 MPa; 0.5-2.5 bar; 7-36 psi produces a
soft jet, which largely eliminates the problem of overlapping boundaries. There is a pos-
sibility to reduce the jet by form air.

ELECTROSTATIC EFFECT

The spray gun produces an electrostatic fi eld by means of the high voltage electrode. As a
result, the particles of paint, which have been atomized by the spray gun, are carried to the
earthed object by kinetic and electrostatic energy where they adhere, fi nely distributed, to
the object being sprayed.

Advantages of electrostatics:
•
Very effi cient spraying
•
Little over spray
•
Coating of entire circumferences due to an electrostatic fi eld
•
Less working time
