Cooler crosslinking. Benefits and limitations of using UV LEDs to cure wood coatings
Radiation curing is established as the technology of choice for many applications in industrial wood finishing. UV LED technology has advanced to the point where it now offers advantages over traditional mercury lamps in this role. UV LEDs emit light only in a very narrow wavelength band, and coating formulations should be optimised for this range. A limitation is that all these wavelengths are in the near-visible or UVA range. Energy efficiency is comparable to that of mercury lamps, but advantages include a very long lifetime, instant start-up and shut-down, the option to illuminate only the working width required at a given time, safer operating voltages and absence of toxic mercury. Economic comparisons are provided showing that the higher initial cost of an LED installation can be recovered rapidly through lower operating costs.
