Abstract:
The present invention provides a conductive, curable coating made from about 0.01 wt. % to about 5 wt. %, of multi-walled carbon nanotubes, having a diameter of greater than about 4 nm, about 10 wt. % to about 99 wt. % of an aliphatic urethane acrylate and about 0.1 wt. % to about 15 wt. % of a photoinitiator, wherein the coating is curable by exposure to radiation and wherein the cured coating has a surface resistivity of about 10Ω/□ to about 10Ω/□. A process for the production of such coatings is also provided. There are many applications where carbon nanotubes in a radiation curable coating may enhance properties other than conductivity, such as physical and thermal properties.
