Towards UV LED curing

We believe UV-LED technology to be the future of UV curing, for it is a lower energy-consuming option than traditional Hg-doped lamps. It is also the technology of choice to coat or print on to heat sensitive substrates.

 

Benefits:

  • Very long lifetime and consistent energy output
  • No infra-red emission ➞ no heat generated
  • No warm-up time required
  • Compact and flexible lamp design
  • No generation of O3
  • Mercury-free system

 

 

Recommended applications:

  • Industrial coatings
  • Graphic arts
  • Food packaging
  • Electronics
  • Adhesives

Specificities and advantages of EB curing

Definition:

EB : electron beam ➞ accelerated e-

 

Benefits:

 

  • No photoinitiators required ➞ minimized migration and low migration
  • High degree of conversion
  • Very high speed achievable allowing deep penetration for thick coatings
  • N2 atmosphere needed to avoid O2 inhibition
  • High energy radiation
  • Improved dot gain control
  • No heat for sensitive substrates
  • Highest performances : gloss, scuff and abrasion resistance
  • Suitable for highly pigmented formulations

 

Recommended applications:
