Light color conductive coatings

A coating composition, comprising:

• a resin;
• and
• up to 10 wt % on a dry basis of at least one CNS-derived material dispersed in the coating composition and selected from the group consisting of:
• carbon nanostructures, fragments of carbon nanostructures, fractured carbon nanotubes, and any combination thereof,
• wherein the carbon nanostructures or fragments of carbon nanostructures include a plurality of multiwall carbon nanotubes that are crosslinked in a polymeric structure by being branched, interdigitated, entangled and/or sharing common walls, and
• wherein the fractured carbon nanotubes are derived from the carbon nanostructures and are branched and share common walls with one another, and
• when tested according to Evaluation Method A, the resulting cured coating has a surface resistivity of at most 107 ohm/square.

A method of producing a coating composition, comprising:

• providing a millbase comprising at least one CNS-derived material dispersed in a solvent and selected from the group consisting of:
• carbon nanostructures, fragments of carbon nanostructures, fractured carbon nanotubes, and any combination thereof,
• wherein the carbon nanostructures or fragments of carbon nanostructures include a plurality of multiwall carbon nanotubes that are crosslinked in a polymeric structure by being branched, interdigitated, entangled and/or sharing common walls,
• wherein the fractured carbon nanotubes are derived from the carbon nanostructures and are branched and share common walls with one another, and
• combining the CNS millbase with a resin to form a coating composition which, when it is tested according to Evaluation Method A, the resulting cured coating has a surface resistivity of at most 107 ohm/square.
