The advantages of pulsed UV light over continuous
mercury UV lamps for curing applications are described in a brochure from Xenon
Corp. The downloadable four-page publication notes that pulsed UV systems provide
better penetration while maintaining low average power, and that they consume up
to 80% less energy than the mercury types. A chart illustrates that pulsed UV light
provides cooling between pulses and that mercury UV curing continuously warms the
substrate. Pulsed UV curing applications include cosmetics packaging, adhesives
and wood coatings, and the manufacture of optical disks and medical electrodes.
