Method for drying of a coating and related device
View Patent ↗A method for drying a coating applied to a substrate, wherein the coating comprises at least one volatile organic solvent (VOS), is provided. The method comprises a step of irradiating the coating by an electromagnetic radiation at a power P and within a defined spectrum, wherein the defined spectrum corresponds to an absorption peak of the volatile organic solvent.
1. A method for drying a nail polish applied to a fingernail, the nail polish including at least one volatile organic solvent (VOS) and at least one non-volatile compound, the VOS having one or more absorption peaks in the Infra-Red (IR) range, the method comprising evaporating the VOS by an electromagnetic radiation that selectively heats the VOS, wherein the electromagnetic radiation is in the range of 1,540 nm-20,000 nm and is substantially spectrally concentrated around the one or more absorption peaks, wherein the one or more absorption peaks are substantially distinct from absorption peaks of the non-volatile compound.
2. The method of claim 1 , wherein the absorption peak is characterized by a peak absorption at least about 1.5 times greater than said average absorption.
3. The method of claim 1 , wherein the electromagnetic radiation is in the range of 8,000 nm-15,000 nm.
4. The method of claim 1 , wherein volatile organic solvent is selected from the group consisting of acetone, ethyl acetate, butyl acetate, ethyl alcohol, butyl alcohol, methyl alcohol, isopropyl alcohol, methyl ethyl ketone, toluene, xylene, and combinations thereof.
5. The method of claim 1 , wherein the VOS comprises 10% to 60% by weight of the nail polish.
6. A device for drying a nail polish applied to a fingernail, the nail polish including at least one volatile organic solvent (VOS) and at least one non-volatile compound, the VOS having one or more absorption peaks in the Infra-Red (IR) range, the device comprising an electromagnetic radiation source configured to radiate an electromagnetic radiation at a wavelength in the range of 1,540 nm-20,000 nm and is substantially spectrally concentrated around the one or more absorption peaks, wherein the one or more absorption peaks are substantially distinct from absorption peaks of the non-volatile compound, thereby evaporating the VOS by selective heating thereof.
7. The device of claim 6 , wherein the electromagnetic radiation is in the range of 8,000 nm-15,000 nm.
8. The device of claim 6 , wherein volatile organic solvent is selected from the group consisting of acetone, ethyl acetate, butyl acetate, ethyl alcohol, butyl alcohol, methyl alcohol, isopropyl alcohol, methyl ethyl ketone, toluene, xylene, and combinations thereof.
9. The device of claim 6 , wherein the VOS comprises 10% to 60% by weight of the nail polish.
10. The device of claim 6 , wherein the device is portable.
