Its thick consistency allows for easy sculpting and shaping, making it ideal for building an arch and creating a curved nail shape.
10.
A___ is a chemical in UV gel resins that initiates the polymerization reaction.
Correct Answer
D. pHotoinitiator
Explanation
A photoinitiator is a chemical compound that triggers the polymerization reaction in UV gel resins. When exposed to UV light, the photoinitiator absorbs the energy and undergoes a chemical reaction, which leads to the formation of free radicals. These free radicals then react with the monomers in the resin, causing them to link together and form a solid polymer network. Thus, the photoinitiator plays a crucial role in initiating and controlling the curing process of UV gel resins.
11.
Which of these is a type of gel used over the finished UV gel to create a high shine?
