[en] The main advantage of this method as compared to the conventional thermal process is that a coating is hardened within fractions of a second. The energy required, as well as the place necessary for an EB system is smaller than usual. After hardening at room temperature, temperature-sensitive substrates such as wood and paper are not thermally stressed. The adherence of the coating on organic-chemical bonding between the molecules of the substrate and their coating is good as a result of radiografting. The process is easy to control. (orig.)
