Magnetic Nail products 2

A

contain iron powder

magnet held close to the nail to formulate the iron powder in desired pattern before evaporation of solvent

102
Q

TSFR 3

A

toluene-sulfonamide-formaldehyde-resin

most common cause of allergic contact dermatitis

toxin free is better but hypoallergenic has increase polish peeling

103
Q

product removal 3

A
  • most damaging service that can be done, even when correct

complete removal causes drying and damage to plate

best to leave enhancements in place maintained and only remove when client doesn’t want them anymore.

104
Q

how many times a year can enhancement removal become damaging 1

A

3-4 times a year

105
Q

nail coatings 1

A

products that cover nail plate with a hardened film

106
Q

two main types of nail coatings 2

A

coatings that cure/polymerize- enhancements, UV gel- chemical reactions

coatings that harden upon evaporation- nail polish, top coats, base coats- physical reactions

107
Q

adhesion 3

A

force of nature that takes 2 surfaces stick together

molecules on one surface are attracted to molecules on another

oils can contaminate- which is why clean dry surface is needed.

108
Q

adhesive 2

A

chemical that causes two surfaces to stick together

allow incompatible surfaces to join

109
Q

nail primer 1

A

substance that improves adhesion

110
Q

polymers 3

A

molecules in product join into extremely long chains

can be liquids but usually solid

proteins are polymers- making a nail plate a polymer

attach selves to tail end of monomer and passing energy along- domino reaction

causes chain to get longer

becomes tangled and knotted- product thickens

chains become much too crowded t freely move and product has become mass of microscopic chains

this is when surface is hard enough to file.
