5. UV Gels • A type of nail enhancement product that hardens when exposed to a UV gel light; an increasingly popular method for nail enhancement services © Copyright 2012 Milady, a part of Cengage Learning.

6. UV Gel Characteristics • Rely on monomer liquid (ML) and polymer powder (PP) ingredients • Part of the family of acrylates • Rely mostly on oligomers – Short chains of monomers not long enough to be considered polymers and often referred to as "prepolymers" © Copyright 2012 Milady, a part of Cengage Learning. All Rights Reserved. May not be scanned, copied, or duplicated, or posted to a publicly accessible website, in whole or in part.

7. UV Gel Characteristics (continued) • Traditional gels: rely on urethane acrylates • Newer gel systems: rely on urethane methacrylates • Reaction: resins react to UV light • Photoinitiator: creates polymerization reaction • Curing: combination of resin, photoinitiator, and curing lamp • Requires UV lamp exposure to cure © Copyright 2012 Milady, a part of Cengage Learning. All Rights Reserved. May not be scanned, copied, or duplicated, or posted to a publicly accessible website, in whole or in part.

8. UV Gel Characteristics (continued) • Easy to apply, file, and maintain • Not as hard as monomer liquid and polymer powder • Viscosity © Copyright 2012 Milady, a part of Cengage Learning.

10. Types of UV Gels • UV bonding gels: used to increase adhesion • UV building gels: use thick viscosity resin • Self-leveling UV gels: provide smoother surface than self-building gels • Pigmented gels: include color © Copyright 2012 Milady, a part of Cengage Learning.

11. Types of UV Gels (continued) • UV gel polishes: cure in UV light unit • UV gloss gels: sealing, finishing, or shine gels – Traditional (with a sticky inhibition layer) – Tack-free (no inhibition layer) – Opacity: amount of colored pigment concentration in a gel © Copyright 2012 Milady, a part of Cengage Learning.
