UV Curable Resins for varnishes such as gel nail products, nail polish (requires UV light to cure and harden) 

UV-Resin F-2F-250 (Urethane Acrylate)

Viscosity: 120-280 cPs (25C)

The curing speed is fast, and it can be surface-dried under the mercury lamp and 120mJ/cm2 energy; it can be surface-dried under the LED light source for 10 seconds.
Good flexibility and good tear resistance.
Good adhesion, good adhesion to PET.
Pigment wettability is good, when the nano color paste is added to more than 10%, it has little effect on curing.

Explanation of product code UV Curable Resins

A=Excellent Adhesion (excellent adhesion to the surface suitable for use as a base coat)

H=Hardness suitable for use as a top coat)

F=Flexibility (flexible) Suitable for use as a base coat)

Y=Yellow Resistance (Ultra yellow resistance)

0F = Functionality 0 (The higher, the higher the Reactivity level, the faster the cure or hardening)

1F = Functionality 1

2F = Functionality 2

3F = Functionality 3 

4F = Functionality 4

6F = Functionality 6

8F = Functionality 9 

last number Refers to the viscosity, such as 2K = 2000cps, 30 = 30cps, 60K = 60000cps.

General Formula of UV Gel Nail

Base Coat:

HPMA  20% (acts as a solubilizer, adjusts the thickness appropriately)

TPO-L  5% (acting as Photoinitiator when exposed to UV light will cause the Resin to harden)

Highly flexible type of resin. and adheres well to nail surfaces such as UV-Resin A-4F-2K 50%

Medium hard resin provides moderate flexibility, for example UV-Resin 2F-30K  10%

Resin type that provides high strength such as UV-Resin H-8F-2K  15%

Color Layer:

HPMA  20% (acts as a solubilizer, adjusts the thickness appropriately) 

TPO-L  5% (acting as Photoinitiator when exposed to UV light will cause the Resin to harden) 

Medium hard resin provides moderate flexibility, for example UV-Resin 2F-30K  5 0% 

Other resins with moderate hardness provides moderate flexibility, for example UV-Resin 2F-7K  15%

Resin type that provides high strength such as UV-Resin H-8F-2K 10% 

Top Coat:

HPMA  20% (acts as a solubilizer, adjusts the thickness appropriately)  

TPO-L  5% (acting as Photoinitiator when exposed to UV light will cause the Resin to harden)

  Resin type that provides high strength such as UV-Resin H-8F-2K  35%

    Resin type that provides high strength, other types such as UV-Resin H-6F-60K  30% 

Resin that adheres well to the skin, such as UV-Resin 1F-30  10%

Use: For UV Gel Nail, nail polish color or other coating work

How to mix: Mix with different types of resin and mix with color (curing time requires UV Lamp for about 60 seconds).

Utilization rate: 1-100% (allowed for nails By acting as a nail color only, not allowed to be used on other parts of the body)

Product characteristics: Colorless or light-colored liquid with a characteristic odor.

Solubility: Able to mix with other UV Curable Resin, Soluble in HPMA , TPO-L

Storage: store at room temperature Avoid sunlight and heat. Aged at least 1 year. In case of being exposed to light, the cure will occur by itself. The passenger will harden and cannot be used.
