Description
2.1
Theory of Operation
The UV Wand System is a high-power lamp system for the curing of UV adhesives. The lamp’s
emission spectrum and radiant power capacity were designed specifically to meet the
requirements of UV-curable Loctite
®
adhesives and coating compounds. Absolutely dry and tack-
free surfaces can be obtained very quickly.
The radiation time must be determined by trial and can be preset to ensure precise repeatability of
curing results. In order to reduce the thermal load on substrates, visible light and IR are filtered.

UV Spectra
Avoid direct radiation of the skin and eyes under all circumstances!
The ultraviolet spectrum is divided into three sections:
UVA
315 nm – 380 nm
UVB
280 nm – 315 nm
UVC
100 nm – 280 nm
UVA is a part of natural sunlight and its most visible effect on human tissue is the tan. Its
intensity is easily underestimated, as it is not visible. An overdose of UVA will not cause a
UV-erythema (sunburn), but a heat-erythema similar to visible light.
UVB is more aggressive than UVA, and also a part of natural sunlight. It has the same
negative effects on human tissue as natural sunlight, the most common being the
UV-erythema (sunburn).
UVC is even more aggressive than UVB, it can cause severe tissue damage with an increased
risk of skin cancer.
