allnex will present its newly designed UV LED booster technologies for many applications including food packaging via a webinar on February 2nd, 2023 (time – 09.00 AM EST/03.00 PM CET.

Our expert,  Jennifer McClung (Technical Service and Business Development Manager/Americas) will present our LED booster technologies, designed specifically to enhance the reactivity of UV LED cure formulation while also considering key regulatory aspects relevant to all applications- but specifically important for food packaging applications.

UV LED curing has become more widespread and continues to exhibit strong growth in the radiation curable market space. Historically dominated by medium pressure mercury vapor lamp technology,  UV LED technology has now greatly  progressed and can offer consistent and acceptable dosage and intensity at a cost competitive to conventional UV curing systems. This has led to the adoption of UV LED cure in many applications including structural bonding adhesives, fiber optics coatings, printing inks, wood coatings and graphics coatings.

To name just a few reasons why  UV LED cure is so attractive to finishers:
 
  • Compact and scalable equipment design
  • Uniform distribution with consistent intensity over time
  • Long service life and reduced maintenance cost
  • Lower operating temperatures
  • Significant reduction in carbon footprint

Despite these numerous advantages, the key to the successful implementation of UV LED cure is the ability to match the adhesive, coating and ink formulations to the specific wavelengths of the UV LED lamps, most commonly 365 nm and 395 nm. Often it is considered that the single most important choice in the formulation is the photo initiator, which is chosen accordingly to match these spectral outputs. However, of equal importance is the consideration of materials that can boost the overall reactivity of these system
