ABSTRACT:
A coating of an exothermically reacting organic substance, which does not have any photoinitiators, applied to a substrate is cured with ultraviolet rays having, among other wavelengths, a wavelength of 197.4 nm. This is accomplished in that sufficient radiation density to initiate the exothermic reaction of the substance is produced at a sufficient distance, with respect to temperature, from a mercury-vapor tube. The mercury-vapor tube employed for producing the ultraviolet rays has a casing of quartz. Means for focussing rays into beams are associated to this tube.
