Introduction

Comprehend the Chemistry of Light Cured Gels

• Oligomer – a short chain of monomer liquids that is often thick, sticky, and gel-like and that is not long enough to be considered a polymer.

• Light cured gels rely on a special type of acrylate called a urethane acrylate, while newer light cured gel systems use urethane methacrylates.

• A chemical within the product, called a photoinitiator initiates the polymerization reaction.

Describe Light Cured Gels

• The different light cured gels– Thin-viscosity gels– Medium-viscosity gels– Thick-viscosity gels

– Building or sculpting gels. • The one-color method – one color of gel is

applied over the entire surface of the nail • The two-color method – two colors of resin are

used to overlay the nail
