Flexible Film –
UV-blocking, flexible urethane films can be used to quickly create workstation shielding.
This UV-blocking, flexible urethane film is available from DYMAX (see Table 1).
HIGH TEMPERATURE SURFACES
Surfaces exposed to high intensity curing lights will rise in temperature. The intensity, distance, exposure time, cooling
fans, and the type/color of the surface can all affect the actual surface temperature. In some cases, exposed surfaces
can reach temperatures capable of producing a burn or causing damage to a substrate. In these cases, care must be
taken to ensure either a more moderate surface temperature or appropriate protection/training for operators.
OZONE
Standard DYMAX bulbs (UVA type) generate an insignificant amount of UVC and therefore essentially no ozone
3
. Some
UV curing systems, like those used to cure UV inks, emit primarily “shortwave” (UVB and UVC) energy. Upon exposure
to UVC light (specifically <240 nm), oxygen molecules (O
2
) split into oxygen atoms (O) and recombine with O
2
to create
ozone O
3
. The current, long-term ozone concentration limit recommended by ACGIH, NIOSH, and OSHA is 0.1 ppm
(0.2mg/m
3
).
BRIGHT, VISIBLE LIGHT
The bright visible light emitted by some UV curing systems can be objectionable to some workers and can cause
eyestrain. Tinted eye protection and/or opaque/tinted shielding can be utilized to address this concern.
SUMMARY
UV light sources can be more “worker friendly” than many commonly accepted industrial processes, provided the potential
concerns are addressed. Contact your DYMAX representative for information regarding the proper use of DYMAX UV
curing systems.
