Investigation of the Conducting Properties of Films Pigmented with Copper
Abstract
Some evidence exists that organic films containing metallic copper pigment sometimes may be expected to perform similarly to a metallic conductor. The present investigation was designed to uncover evidence to clarify this point of view. A number of experiments are described in which efforts have been made to study the electrical conductivity of anti-fouling paint compositions covering a wide range of pigment volumes. The data indicate that at high pigment volume the conductivity of the film is of a sufficiently high order as to accelerate the corrosion of steel to which it is coupled through a metallic conductor. Further evidence is presented to show that paint films which provide cathodic areas blister and fail more rapidly than non-conducting films. Additional experiments are recommend to expand this investigation to include cuprous oxide paints.
