Growth of the nail would be the only practical but unsightly manner of removal of such a polymer coat. Once applied, it could not be removed from a nail. ![]() However, a nail polymer coat that mimics the ingredients, concentrations and extent of crosslinking of auto polymer coats, would be highly undesirable. ![]() These qualities are benefits for most fields because they provide permanent, impervious, non-removable, strong but flexible protective coatings for metals and other substrates that would otherwise be susceptible to environmental degradation.īecause these same coatings are used for nail coatings, these beneficial attributes for other commercial fields such as auto polymer coats become problematic for nail polymer coats. The result of extensive crosslinking of these compositions produces coatings that are impervious to all manner of attack including scratching, chipping, organic solvents, abrasives and ordinary environmental activity. Strength of the crosslinked or photopolymerized compositions is also increased by use of urethane (carbamate) chains within the three dimensional structure of the polymerized composition. The monomeric components of coats not only are polymerized into long carbon chains by photolytic action but are also crosslinked with carbon chains between these chains through the use of di, tri and tetra (meth)acrylate oligomers. Photopolymerizable (meth)acrylate coatings find significant applications in diverse commercial fields including not only nail coatings but also as paints and coatings for automobiles, commercial vehicles, trains, appliances, and metal structures such as steel fabrications. Nail salons are the typical commercial establishments handling this work because it entails careful application and curing by UV radiation. The gels include crosslinkers that contribute hardness, resistance to dissolution, resistance to scratching and long wear yet in combination with film formers contribute flexibility. Recent developments in the technology combine pre-existing film forming polymers such as cellulose acetate butyrate with photopolymerizable gels based upon (meth)acrylate technology. BACKGROUNDĬommercial gel nail coatings typically include a base coat, a color coat and a top coat. 22, 2016, which is herein incorporated by reference in its entirety. 28, 2018, which claims the benefit of priority from U.S.
