Inks and varnishes
Challenges
Continued growth in markets such as UV labels and UV inks for flexible packaging
Constantly more regulatory requirements to support the food packaging industry
Technical developments driven towards better curing response and lower viscosities

Analogue: combination of high reactivity and low shrinkage materials for flexo printingHigh performance UV cure resins for printing inks
Sartomer has developed a full range of specialty acrylate resins to offer solutions for the complete set of UV printing technologies:
- Inkjet
- Offset
- Flexo
- Screen
- OPV
A pioneer in the development of specialty acrylates for UV LED curing systems
We believe UV LED technology to be the future of UV printing, for it is a lower energy-consuming option than traditional Hg-doped lamps. UV-LED lamps offer a narrow but intense spectral emission, which requires highly functional reactive material, available in our product range.
A strong expertise and anticipation of evolving regulations and directives:
- A full and personalized support to address REACH market transition
- Compliance with most influential brand owner’s requirements (BPA free, organotin free, PETIA free solutions)
- Low migration LM range of products for food packaging applications, being
guaranteed to be compliant with the Swiss list and Nestlé guidance notes, with no risk
of contamination and a very low potential for migration.
Final formulations can be designed to meet a wide variety of performance properties.
Sartomer strives to be at the forefront of the UV, UV LED and EB curable marketplace and looks forward to discussing your ideas.
Meet the challenge in very diverse application fields
