  • Publication number: 20080003372
    Abstract: A method of curing free-radically curable compositions under an inert gas atmosphere, where the curing, which proceeds in accordance with a free-radical mechanism, is initiated, or initiated and maintained, in the free-radically curable compositions by radiation and the lateral escape of the inert gas atmosphere is prevented, which involves (1) immersing the free-radically curable compositions in an inert gas atmosphere below a depth from which the inert gas atmosphere constantly exhibits its lowest oxygen concentration, and (2) irradiating the free-radically curable compositions below this depth in the inert gas atmosphere, at least one of the radiation sources being arranged beneath the inert gas/air interface, and then (3) emersing the resultant cured compositions again from the inert gas atmosphere, and apparatus (1) according to FIG. 1 for its implementation.
