Modeling gel is a material with a medium or more fluid consistency and pronounced self-leveling properties. It ensures fast workflow, is ideal for no-file techniques, but requires control to prevent flooding.
Polygel (acrygel) is a thick, moldable hybrid of gel and acrylic. It does not run, allows precise architecture and length building, and provides greater control, density, and rigidity.
Let’s compare Kodi Professional acrygels/polygels:

Texture & Performance:
-
Dense material with high thixotropy (becomes more pliable when worked with a brush).
-
Does not run and holds the desired shape well.
-
Precisely fixes the free edge — ideal for sculpted French designs.
Strength:
-
Very high, thanks to the combination of acrylic and gel properties.
-
Resistant to mechanical stress.
Best for: strengthening natural nails, sculpted French, corrections, modeling any length and complex shapes.
Shade range: 6 shades (including clear).
Key feature: perfect for creating precise architecture and long nails.

Texture & Performance:
-
Fine-grained formula.
-
High elasticity and resilience.
-
Distributes comfortably, creating a smooth surface.
-
Holds apex height well.
Strength:
-
Combines flexibility and rigidity.
-
Easy to file during correction.
Best for: extensions, repairs, corrections, strengthening thin and weakened nails, working with upper and lower forms or without forms.
Shade range: nude and colored shades.
Key feature: a universal balance between strength and elasticity.
Let’s compare Kodi Professional modeling gels:

Texture & Performance:
-
Medium-viscosity hard polymer.
-
High thixotropy — does not run at rest but distributes easily during application.
Strength:
-
Rigid material that holds the arch well.
-
Suitable for length building and strong reinforcement.
Best for: leveling, extensions, corrections, sculpted French, working with forms.
Shade range: 13 nude shades (classic collection) + 5 glitter shades (Shine collection).
Key feature: a versatile product suitable for various techniques.

Texture & Performance:
-
Medium-viscosity, comfortable consistency.
-
Good thixotropic properties.
-
Suitable for no-file techniques.
Strength:
-

Best for: strengthening, leveling, modeling.
Shade range: 2 nude shades + clear.
Key feature: ideal for sensitive clients due to a low exothermic reaction — minimal heat during curing.

Texture & Performance:
-
Medium consistency.
-
Distributes evenly, minimizes the risk of flooding.
-
Suitable for no-file techniques.
Strength:
-
High resistance to chipping.
-
No shrinkage.
Best for: extensions, strengthening, leveling.
Shade range: nude and colored shades.
Key feature: fast salon results with minimal finishing.

Texture & Performance:
-
Medium-viscosity material with pronounced self-leveling properties.
-
Easy to control, does not run.
-
Pinches well and forms a defined arch.
Strength:
-
Maintains shape reliably after curing.
Best for: no-file techniques, working with upper forms, leveling and modeling.
Shade range: nude shades.
Key feature: ideal for creating correct nail architecture with minimal effort.
