Artificial nail tip and curing composition set and applying method thereof
A nail tip curing composition includes an Extend Gel, an edge-off flat brush, a nail filing device, a plurality of GEL-X tips, a pH Bonder, and a Non-Acidic Gel Primer. The pH Bonder forms a pH Bonder layer on a surface of a fingernail. The Non-Acidic Gel Primer forms a Non-Acidic Gel Prime layer overlapped on the pH Bonder layer. The Extend Gel forms an Extend Gel layer overlapped on the Non-Acidic Gel Prime layer. The GEL-X tip is filed by the nail filing device and the Extend Gel is applied on an underside contact surface of the Gel-X tip by the edge-off flat brush. The underside contact surface of the Gel-X tip is contacted with the Extend Gel layer on the fingernail in such a manner that the Gel-X tip is firmly affixed on the fingernail.
1. A method of applying an artificial nail tip made of acrylic material on a fingernail, the method comprising:
(a) applying a layer of adhesive composition to the top surface of a fingernail, wherein the adhesive composition consists of:
75.0-80.0% by weight of polyurethane acrylate oligomer,
10.0-15.0% by weight of 2-hydroxyethyl methacrylate (HEMA),
1.0-5.0% by weight of 1-hydroxycyclohexyl phenyl ketone, and
1.0-5.0% by weight of phenylbis(2,4,6- trimethylbenzoyl)phosphine oxide;
(b) applying a layer of adhesive composition to the underside contact surface of an artificial nail tip;
(c) gradually pressing the artificial nail tip onto the top surface of the fingernail, from the base to the tip of the artificial nail tip, to ensure a tight seal and to prevent air bubbles;
(d) continuing to press the artificial nail tip onto the top surface of the fingernail while applying UV or LED light to the artificial nail tip;
(e) after removal of pressure, applying UV or LED light to the artificial nail tip for a length of time sufficient to completely cure and harden the adhesive composition and form a bonding layer between the artificial nail tip and the fingernail;
wherein the bonding layer affixes the artificial nail tip to the surface of the fingernail for at least two weeks.
2. The method of claim 1 , wherein the length of time to completely cure and harden the adhesive composition is about 30 seconds to about 2 minutes.
3. The method of claim 1 further comprising a step of filing the underside contact surface of the artificial nail tip with a nail filing device to form a rough affixing surface, before applying the adhesive composition in step (b).
4. The method of claim 3 , wherein the rough affixing surface formed on the underside of the artificial nail tip has multiple small, indented grooves thereon.
5. The method of claim 1 further comprising the steps:
(i) applying a pH bonder to the top surface of the fingernail to form a pH bonder layer;
(ii) air drying the pH bonder layer;
(ii) applying a non-acidic gel primer layer on top of said pH bonder layer;
(iv) air drying the non-acidic gel primer layer;
wherein the pH bonder and non-acidic gel primer layers are applied to the fingernail prior to application of the adhesive composition in step (a).
6. The method of claim 4 further comprising the steps:
(i) applying a pH bonder to the top surface of a fingernail to form a pH bonder layer;
(ii) air drying the pH bonder layer;
(ii) applying a non-acidic gel primer layer on top of said pH bonder layer;
(iv) air drying the non-acidic gel primer layer;
wherein the pH bonder and non-acidic gel primer layers are applied to the top surface of the fingernail prior to application of the adhesive composition in step (a).
7. The method of claim 5 further comprising the step:
(f) applying a top coat composition to the artificial nail tip, wherein the top coat composition consists essentially of:
35.0-50.0% by weight of polyurethane acrylate oligomers;
15.0-30.0% by weight of 2-hydroxyethyl methacrylate (HEMA);
10.0-25.0% by weight of di-trimethylolpropane tetraacrylate;
5.0-10.0% by weight of pentaerythritol tetra(3-mercaptopropionate) (PETMP); and
0.0-1.0% by weight of polyether-modified polysiloxane.
8. The method of claim 6 further comprising the step:
(f) applying a top coat composition to the artificial nail tip, wherein the top coat composition consists essentially of:
35.0-50.0% by weight of polyurethane acrylate oligomers;
15.0-30.0% by weight of 2-hydroxyethyl methacrylate (HEMA);
10.0-25.0% by weight of di-trimethylolpropane tetraacrylate;
5.0-10.0% by weight of pentaerythritol tetra(3-mercaptopropionate) (PETMP); and
0.0-1.0% by weight of polyether-modified polysiloxane.
