Abstract
A composition for adhering to human nails includes a mixture of a cyanoacrylate compound and/or graphite fibers. Such composition can take the form of either an artificial nail extender or a nail coating. The composition for forming an artificial nail includes graphite fibers, a cyanoacrylate, and a hardening accelerator containing a mixture of trichlorotrifluoroethane and N,N-dimethyl-P-toluidine. The accelerator is adapted to be sprayed onto a base material containing the graphite fibers and cyanoacrylate in the form of a mist. Nail compositions containing graphite fibers have significantly increased strength yet remain flexible to allow for flexure of the nail. The cyanoacrylate compounds increase the chemical bonding of the compositions to a nail.
