UV-cross linking under Oxygen-reduced conditions

It is not since today that we know the application of UV-curing under oxygen-reduced, inert conditions. For the cross-linking of silicones manufactured by Goldschmidt it is imperative to keep the residual oxygen content below 50 ppm. Particularly by the end of 1999, the demand for UV units running under oxygen-reduced conditions increased for the food packaging sector. The benefit is up to reduced photoinitiator proportion of UV-inks and varnishes combined with odour reduction and increased production safety.
