Features of "Neojet"

Inkjet Discharge

It is possible to control the stability of inkjet ejection by adjusting the viscosity and other liquid properties of the UV curable resin.

  • Control of dispensing stability is possible by adjusting liquid properties.

UV-LED Curability

"Neojet" products are also compatible with LED light sources. 
Curing with an LED light source not only saves energy, but also reduces damage to PP and PE films that are damaged by heat during UV irradiation with ordinary high-pressure mercury lamps and metal halide lamps. 

  • Compatible with UV-LED curing 
  • Good UV curability even under atmospheric conditions

High Adhesion

UV Resin Adhesion Issues

When UV curable resins are applied to base materials such as glass and various films and irradiated with UV light to form a cured film, curing shrinkage occurs and stress inside the film causes the cured film to peel off from the base material. In particular, non-polar base materials such as polyolefin (PP, PE) tend to have low affinity with UV curable resins and poor adhesion. 

To address this issue, we have formulated a compound with a high affinity for base materials that we have uniquely designed, and by further reducing curing shrinkage, we have achieved adhesion to non-polar polyolefin base materials, glass, and metals, respectively. 

"Neojet PAD" (Olefin Adhesion) 

This grade has high adhesion to non-polar base materials such as polyolefins and exhibits high adhesion by bringing its SP value close to that of polyolefins. This product is suitable for primers and coating materials for various films. 

"Neojet GMAD" (Glass Adhesion)

This grade has good adhesion to glass and metals and is suitable for protective and insulating films for metal wiring.

High Toughness ("Neojet FL")

Challenges in Achieving both Hardness and Elongation

In recent years, UV curable resins that combine hardness (hardness and elastic modulus) and elongation have been required for various flexible electronic materials, foldable smartphones, and decorative films for automobile interiors, but it has been difficult to satisfy these requirements with conventional UV curable resins.

"Neojet FL" Products

Our tough UV curable resin "Neojet FL" is a grade that combines hardness and elongation and has excellent molding processability due to its hardness and resistance to cracking after curing. 

 They are suitable for optical films and protective materials for various electronic components.
