Cure Monitoring of Near-UV Cured Gel Nail Polish

Lambient Technologies tested the base gel for a nail polish system that requires near-ultraviolet light to cure. Normal use of gel nail polish consists of application of a base gel, color gel then top gel to the fingernail. As recommended by the manufacturer, each coat requires exposure to blue-violet LED illumination for 45 seconds to cure before application of the next layer. The base gel was brushed onto Varicon sensors and tested with three lamps: “Normal,” “Wave” and “Gradual” to determine whether the cure times change under different illumination schedules.
