The two main components of Gel nails are the Photoinitiators and the UV light.
Photoinitiators are the oligomers and the monomers. With this mixture, when put under the UV light it starts the polymerization process.
UV light is the other main component and controls how the Gel will stay on the nail and makes the Gel connect onto the nail. The UV light starts the polymerization process when the Gel is put under the UV light. The UltraViolet light also lands on the light spectrum at about 400 wavelength and in between X-ray and Infrared. Also UV lights are an electromagnetic radiation.
Shellac’s two main components are Radical initiators and Methacrylate monomers.
Radical Initiators are a substance that can produce radical reactions under mild conditions. The radical reactions, is the Shellac connecting to the natural nail, under the UV light.
Methacrylate are monomers that easily form polymers because the double bonds are very reactive. Its used on nails because it gets hard and dry fast when put under the ultraviolet light.
