  • Paints that can be cured by UV light usually contain so-called photoinitiators. These photoinitiators are transformed into radicals by the UV light acting on the paint. These radicals cause a chemical reaction in the paint. In this reaction, polymer chains of the binder are broken. This creates a netting, which leads to a high strength of the paint layer and in particular causes a high scratch resistance of the surface of the paint layer.

Le dispositif comporte une source de rayonnement (208). Il comprend au moins un élément optique (206) pour l'acheminement sur l'objet (252) du rayonnement (212) provenant de la source de rayonnement (208). Selon l'invention, ledit ou lesdits éléments optiques (206) sont incorporés dans un dispositif de manipulation (228), au moyen duquel, pour le réglage du chemin optique entre la source de rayonnement (208) et l'objet (252), l'élément optique (206) peut être déplacé par rapport à la source de rayonnement (208) et par rapport à l'objet (252).
