The State of UV-LED Curing: An Investigation of Chemistry and Applications

Image 1 Wavelength Mercury Lamp Narrow Web Feb2016
Light-emitting diodes for ultraviolet-curing applications (UV-LEDs) have been commercially available for nearly 10 years. However, their unique output characteristics require newly formulated UV chemistries in order to take advantage of UV-LEDs’ many benefits. Read more »

UV LED Curing for Narrow-web Applications

UV LED Wavelength Comparison
UV LED curing refers to a technique which utilises »energy« output from the light emitting diodes (LEDs) in the Ultraviolet (UV) spectrum to treat inks, coatings, adhesives and other UV curable materials. The energy generated by the UV light triggers the chemical reaction resulting in polymerisation of the material thus hardening (or curing) the material. Traditionally, Mercury-based UV lamps have been utilised for curing, but now more energy efficient and environmentally friendly LED-based UV technology has proven a superior solution to the printing industry.

UV LED Technology Update

Adhesive Label Curing Fw
UV curing technology is utilized for drying inks, coatings, adhesives and other UV-sensitive materials through polymerization. UV LED curing improves on the existing UV process by enabling thinner, heat-sensitive substrates, while eliminating harmful byproducts such as ozone, and improving workplace safety. Read more »

A rapid cure with LED

Phoseon LED Benefits
The term ‘UV curing’ has been around for a very long time, but UV ‘LED’ curing is a newer concept that has emerged into the marketplace. Dr Richa Anand of Phoseon Technology presents her company’s view. — UV LED technology is unique because it utilises an ultraviolet electronic light source with LEDs (light emitting diodes) for drying inks, coatings, adhesives and other UV sensitive materials through polymerisation instead of evaporation. These solid state devices provide instant on-off ability with no warm up time or mechanical shutters. The rapid growth of this technology continues as more and more OEMs and end users become aware of the substantial benefits of the technology. Read more »
