Use of Size Controlled Conductive Particles to Achieve a Controlled
Resistance Conductive Paint
Described is a technique allowing more precise and economical formulation
of conductive paint with controlled resistance.
At a constant weight fraction of filler, variations in conductive properties can
be obtained and thereby controlled by choosing different sizes of filler particles.
Using smaller particles as conductive fillers raises paint resistance, and higher
resistance enables paint to dissipate potentially injurious electrical discharges.
The best results, in terms of dissipating electrical discharge to a machine
tabletop, was obtained using particles of nickel that passed through a 325 mesh
screen (i.e., less than 0.0017 in) in a mixture of 0.25 gm of nickel per ml of epoxy
The mechanism probably involves the packing arrangement of the particles in
the cured paint film. It can be argued that the smaller particles are less likely to
touch each other than larger ones would, and that this fact causes an increased
resistance to electrical current passing through the film by increasing the
effective path length to ground.
