Which of the following substances can be flash-cured?

Flash-curing is a technique used primarily with UV gel products to quickly harden or set the material using a specific light source, typically a UV lamp. This process allows nail technicians to shape and manipulate the gel before it fully cures, offering increased flexibility and ease of application.

UV gel is designed to respond positively to UV light, making it the ideal choice for flash-curing. This rapid curing process can improve efficiency in nail services, allowing for faster application times and less waiting for products to dry.

Other substances, while also used in nail services, do not undergo the same flash-curing mechanism. Acrylic powder requires a chemical reaction with a liquid monomer to harden, which involves a different curing process. Silicone resin, though it can have varying curing methods, generally does not rely on flash-curing techniques associated with UV light. Nail polish, on the other hand, typically dries through solvent evaporation rather than curing under UV light. Thus, the choice of UV gel stands out as the only suitable option for flash-curing in this context.
