ABSTRACT:
The present invention is a process for protecting articles from electrostatic discharge (ESD) in which a coating is applied directly onto the article in liquid form and the resulting coating provides a surface resistivity that protects the underlying article from ESD. The composition contains a carrier material, carbon black, and a transition metal. The composition forms a coating on an article when applied as a liquid and dried thereon. The ratio of carrier solids to carbon black is about 100 parts by weight polymer to about 0.5 to about 3 parts by weight carbon black. The ratio of carrier solids to transition metal is about 100 parts by weight about 6 to about 15 parts by weight transition metal.
