UV LED curing has become more widespread and continues to exhibit strong growth in the overall radiation curable market space. Historically the radiation curing space was dominated by medium pressure mercury vapor lamp technology, but UV LED technology has continued to progress 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.
There are many reasons why UV LED cure is attractive to finishers. Among these advantages are –
- 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
Even with 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 photoinitiator, which is chosen accordingly to match these spectral outputs. However, probably of equal importance is the consideration of materials that can boost the overall reactivity of these system.
In this webinar, we address this aspect of formulation presenting allnex’s LED booster technologies, which are 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.
