epoxy siloxane

They are advantageous because they do not soften until the technician pushes them or brushes them into place.
b)
They are usually very difficult to file.
c)
They move or lose shape before curing.
d)
They are thin-viscosity bonding gels and harden without a curing lamp.
13.
Identify an accurate statement about ultraviolet (UV) florescent bulbs used in a curing lamp.
a)
UV florescent bulbs radiate light inside the lamp so all nails are equally exposed in ranges from about 320 to 400 nm.
b)
The range of UV florescent bulbs is wider than that of LED bulbs.
c)
UV florescent bulbs typically stop glowing after six months of use.
d)
Most manufacturers recommend changing the UV florescent bulbs inside a curing lamp every year.
14.
Which of the following points should be kept in mind when discussing hard gel extensions with a client?
a)
Since gels can only be filed off, they are not the best option for a short-term extension service.
b)
If the extension edge will be shorter than the nail bed, it is best to choose a stronger product, such as liquid and powder.
c)
Gel services have weak adhesion, making them the last option for clients whose nails lift easily.
d)
Hard gel extensions can be easily removed with acetone or product remover.

light-cured gels, invented in the 2010s, are a new addition to the nail industry
19.
Which of the following statements related to gel chemistry is accurate?
a)
An exothermic reaction occurs as each bond of a polymer is created.

The more bonds formed when a gel cures, the less heat is generated.
c)
The more bonds created when a gel polymerizes, the weaker the nail enhancement.
d)
Gels need photoinitiators to help them transform from a solid to a liquid.
20.
Identify a point that should be kept in mind when discussing gel polishes with a client.
a)
If changing the polish color often is preferred, gel polish is preferred over traditional polish.
b)
Traditional polish is stronger than gel polish because traditional polish provides extra strength to the natural nail.

If wearing the same color for longer periods is preferred, traditional polish is the right fit because it remains chip-free for two weeks.

LED lamps cure slower than do UV bulbs, and this results in fitting less clients into a cosmetologist's schedule.
d)
The range of ultraviolet UV bulbs is wider than that of LED bulbs.
22.
