EDITOR’S NOTE All artificial nail enhancements
products are based on ingredients from the acrylic family
Sub-branch called “methacrylate”Two-part liquid and powder
enhancement systems “Acrylic” – general term for large
group of ingredients

Liquid and powder artificial nail enhancements products based on the methacrylate subcategory
Two-part liquid and powder enhancement system referred to as acrylic (methacrylate) nails

INTRODUCTION Acrylic (methacrylate) nail
enhancements created by combining: monomer liquidpolymer powder
Liquid and powder system

MONOMER “Mono” means “one” “Mer” stands for “units” Monomer is one unit called a
“molecule”
![Page 6: Acrylic (Methacrylate) Nails](https://reader036.vdocuments.net/reader036/viewer/2022081422/568165f5550346895dd91a44/html5/thumbnails/6.jpg)
POLYMER “Poly” means “many “Mer” stands for “units” Polymer means “many units” or “many
molecules”

“LIQUID AND POWDER NAIL ENHANCEMENTS” Applied three basic ways
Natural nail as protective overlayOver nail tipSculpted to extend natural nail using a
flexible form Natural hair brush best to apply
productsSable is best
![Page 8: Acrylic (Methacrylate) Nails](https://reader036.vdocuments.net/reader036/viewer/2022081422/568165f5550346895dd91a44/html5/thumbnails/8.jpg)
Brush immersed in monomer liquid Natural hair bristles absorb and hold
monomer like a reservoir Tip of brush touched to surface of dry
polymer powder
![Page 9: Acrylic (Methacrylate) Nails](https://reader036.vdocuments.net/reader036/viewer/2022081422/568165f5550346895dd91a44/html5/thumbnails/9.jpg)
Monomer absorbs polymer – small bead is formed
Bead is carefully placed on the nail surface and molded into shape with brush
Liquid is usually made from ethyl methacrylate monomerCan contain other monomers used as
customizing additives
![Page 10: Acrylic (Methacrylate) Nails](https://reader036.vdocuments.net/reader036/viewer/2022081422/568165f5550346895dd91a44/html5/thumbnails/10.jpg)
Polymer powder is also made ethyl methacrylate monomer
Polymer powder is made using a special chemical reaction called polymerization
ProcessTrillions of monomers linked together to
create long chainsLong chains create tiny beads of polymer
used to create certain types of artificial nails
![Page 11: Acrylic (Methacrylate) Nails](https://reader036.vdocuments.net/reader036/viewer/2022081422/568165f5550346895dd91a44/html5/thumbnails/11.jpg)
Special additives blended into both liquid and powderEnsure complete set or cureMaximum durabilityColor stabilityShelf life
Liquid is picked up by brush and mixed with the powderBead forms on the end of brush and
quickly hardensTo happen special additives called
catalysts
![Page 12: Acrylic (Methacrylate) Nails](https://reader036.vdocuments.net/reader036/viewer/2022081422/568165f5550346895dd91a44/html5/thumbnails/12.jpg)
CatalystAdditive designed to speed up chemical
reactionsAdded to monomer liquid Used to control the set or curing time
Monomer liquid and polymer powder combined the catalyst helps control the set-up or hardening time
Energizes and activates the initiators Initiators start a chain reaction that
leads to the creation of fantastically long polymer chains
![Page 13: Acrylic (Methacrylate) Nails](https://reader036.vdocuments.net/reader036/viewer/2022081422/568165f5550346895dd91a44/html5/thumbnails/13.jpg)
Polymerization process begins the second the liquid in the brush picks up powder from the container and forms a beadDominos
![Page 14: Acrylic (Methacrylate) Nails](https://reader036.vdocuments.net/reader036/viewer/2022081422/568165f5550346895dd91a44/html5/thumbnails/14.jpg)
INITIATOR Added to polymer is called benzoyl
peroxide (BPO) Over the counter acne medicineDifferent purpose in nail enhancements
BPO used to start chain reaction that leads to curing (hardening)
![Page 15: Acrylic (Methacrylate) Nails](https://reader036.vdocuments.net/reader036/viewer/2022081422/568165f5550346895dd91a44/html5/thumbnails/15.jpg)
Some monomers require more BPO than othersUse polymer powder designed for use with
monomer liquid Using wrong powder can create
enhancements that are not properly cured Could increase risk of client developing
skin sensitivity or irritation

MAINTENANCE AND REMOVAL OF ACRYLIC (METHACRYLATE) NAIL ENHANCEMENTS Regular maintenance prevents nail
enhancements from lifting or cracking If lifting/breaking greater risk of
infection and other problems Full and proper rebalance must be
performed every 2 – 3 weeks
![Page 48: Acrylic (Methacrylate) Nails](https://reader036.vdocuments.net/reader036/viewer/2022081422/568165f5550346895dd91a44/html5/thumbnails/48.jpg)
REBALANCING Method for maintaining the beauty,
durability, and longevity of artificial nail enhancements
Do not let clients go too long without proper rebalance - more repairs
Nail is thinned down –apex of nail removed – entire nail enhancement reduced in thickness
Procedure pages 768 – 769 / 916 - 918Caution box page 769 / 917
![Page 49: Acrylic (Methacrylate) Nails](https://reader036.vdocuments.net/reader036/viewer/2022081422/568165f5550346895dd91a44/html5/thumbnails/49.jpg)

REMOVAL Perform as soon as possible after
request is made Procedure pp 771 921 - 922 Condition surrounding skin with nail
oil/lotion

ODORLESS ACRYLIC (METHACRYLATE) PRODUCTS Same chemistry as all other monomer
liquid and polymer powder Instead of using ethyl acrylic
(methacrylate) – rely on monomers with little odor
Must be used with a dry ix ratioEqual parts liquid to powder in bead
If too wet – skin irritation /sensitivity “snowy – appearing” bead on brush Lift brush and tap gently to remove
excess powder
![Page 52: Acrylic (Methacrylate) Nails](https://reader036.vdocuments.net/reader036/viewer/2022081422/568165f5550346895dd91a44/html5/thumbnails/52.jpg)
Never rewet the brush with monomer Will dilute the enhancement product
already placed on nail Create wrong mix ratio Odorless harder more slowly Creates tacky layer - “inhibition” layer After hardening – remove using
alcohol, acetone or mfg. product Can be filed away Avoid skin contact
