Abstract: Normally, cyanoacrylates cannot be applied by brushing since they cure rapidly in contact with brush bristles. By pre-wetting the bristles with a solvent, this curing action is impeded. Thus, brushes so treated can be stored in a cyanoacrylate monomer formulation and the formulation can be brushed.This discovery permits cyanoacrylates to be conveniently packaged in a bottle with cap and brush ready for use, for example, as fingernail strengthening and extension systems. Thus, sophisticated fingernail enhancement systems can be distributed and used about as conveniently as fingernail polish systems.
