The UV nail gel technology has its roots in the UV cure dental restoration and industrial coatings application areas. The uniqueness of the UV chemistry allows the UV nail gel product the ability to cure the UV nail gel products in minutes vs hours for the conventional nail polish lacquer. In addition, the crosslinking of the UV nail gel results in a coating that will last multiple weeks vs. days for the traditional nail polish lacquer. UV cure light sources have evolved since the introduction of the UV nail gel product that used the GA-FL units which are now being displaced with the newer UV LED technology. Oligomeric, monomeric and PI technology also needed to be developed that was able to override the oxygen inhibition and the use of pigmentation for the UV nail gel technology. Initial introduction of UV nail gel technology was centered around the 100% solids oligomer and monomer technology but has now seen newer introductions of water-based UV cure polyurethane dispersions. In addition, bio-based UV nail gel technology has seen introduction of 100% solids and UV cure polyurethane dispersions.

As with any coating’s technology, the UV nail gel technology also needed to understand surface free energy, adhesion, mechanical properties and removal techniques. Alternative use for the UV nail gel technology is as a solution to remedy toe-nail fungus.UV cured nail gel safety has also become an issue. Testing of the UV cure light sources, oligomers, monomers, PIs and removal techniques of the cured coating have been investigated and continue to be investigated especially as newer products are introduced.

The UV cured nail gel technology is unique and has seen a rapid growth in the nail polish marketplace.
