Abstract
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.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
47 words
A method of applying cyanoacrylate to a selected surface, said method comprising the steps of: pre-wetting the bristles of a brush with a solvent for cyanoacrylate; immersing the bristles of the pre-wetted brush with a cyanoacrylate monomer formulation; and brushing the cyanoacrylate formulation onto a selected surface.
Claim 2
Independent Claim
47 words
A method of applying cyanoacrylate to a selected surface, said method comprising the steps of: pre-wetting the bristles of a brush with a solvent for cyanoacrylate; immersing the bristles of the pre-wetted brush with a cyanoacrylate monomer formulation; and brushing the cyanoacrylate formulation onto a selected surface.
Claim 3
Dependent Claim
13 words
The method of claim 1 further characterized in that the solvent is acetonitrile.
Claim 4
Dependent Claim
23 words
The method of claim 1 further comprising the step of damp drying the solvent after the pre-wetting step and before the immersion step.
Claim 5
Dependent Claim
19 words
The method of claim 1 iterated, with each application of cyanoacrylate defining the selected surface for the next application.
Claim 6
Dependent Claim
14 words
The method of claim 1 further comprising the step of curing the brushed cyanoacrylate.
Claim 7
Dependent Claim
19 words
The method of claim 1 further comprising the step of applying an accelerator to the cyanoacrylate formulation after brushing.
Claim 8
Dependent Claim
17 words
The method of claim 6 further characterized in that the accelerator is sprayed onto the cyanoacrylate formulation.
