Abstract

Dry powder mixtures having components of different size and weight can be successfully sprayed onto a surface by electrostatic spraying techniques, without clumping or agglomeration, provided the nozzle and spray pathway be directed so that electrostatic attraction and/or repulsion is substantially responsible for changing the particle direction and effecting impact with the target electrode (the surface),

Dry powder mixtures having components of different size and
weight can be successfully sprayed onto a surface by
electrostatic spraying techniques, without clumping or
agglomeration, provided the nozzle and spray pathway be
directed so that electrostatic attraction and/or repulsion
is substantially responsible for changing the particle
direction and effecting impact with the target electrode
(the surface),

By regulating the potential, the spray direction and distance
from the target electrode to the nozzle, it is further
possible to avoid deposition (i.e. impact) of any coarse,
undesirable particles since their momentum carries them
beyond the target area despite attractive electrostatic
forces,
